CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Provisional U.S. Patent Application No. 63/224,813, filed Jul. 22, 2021, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

Surgical procedures may generate surgical procedure data, such as data associated with a patient. The surgical procedure data may be generated by surgical instruments, surgical equipment, and/or the like. The surgical procedure data may be processed, for example, for interpretation, analysis, and/or storage purposes.

Interpreting and/or analyzing processed surgical procedure data without knowledge of the processing performed on the surgical procedure data may be difficult. For example, surgical procedure data may have been processed using previous versions of transforms and/or algorithms than are currently used. Interpretation and analysis of the processed surgical procedure data may be inaccurate without knowledge of the exact processing performed on the surgical procedure data.

SUMMARY

Systems, methods, and instrumentalities are disclosed for data processing and creating a record of the processing for archival in metadata associated with the results of the processing. The processing may include transformations of the data. Transforming the data may generate transformed data. The processes performed may be archived, for example, in metadata associated with the transformed data. The metadata may be annotated with information associated with previous transforms performed on the transformed data. The metadata may be stored with the transformed data.

For example, a surgical hub may obtain surgical procedure data, which may be associated with a patient. The surgical hub may obtain the surgical procedure data from one or more of a module associated with the surgical hub, a surgical system located in the OR, and/or the like. The surgical hub may process the obtained surgical procedure data. For example, the surgical hub processing the surgical procedure data may include transforming the surgical procedure data. The surgical hub may generate transformed surgical procedure data using a transform. The surgical procedure may generate metadata, which may be associated with the transformed surgical procedure data. The metadata may include the information associated with the processing (e.g., transform) performed on the surgical data that generated the transformed surgical procedure data. The metadata may include information such as a time associated with the processing of the surgical procedure data, a location associated with the processing of the surgical procedure data, information indicating a portion of the surgical procedure data that was processed, a revision of the transform used to perform the transformation, and/or the like. The surgical hub may process the surgical procedure data and/or generate metadata associated with the transformed surgical procedure data, for example, using blockchain recording. The surgical hub may store the transformed surgical procedure data and the metadata comprising the processing information.

The surgical hub may include a scalable processing system, for example, that may cooperatively interact and process data from other couple hub modules and systems within the OR. The processing may include a transformation or algorithm to combine or compile multiple data elements together. The metadata attached to the transformed data may include information about the transform(s) used on the data.

For example, the surgical hub may obtain previously stored transformed data, such as previously stored transformed surgical procedure data, and metadata associated with the previously stored transformed data. The surgical hub may process the previously stored transformed data. The surgical hub may generate updated metadata associated with the transformation of the previously stored transformed data. The updated metadata may include the previously performed transformations and/or processing on the data before it was obtained and the updated metadata may include the transformation just performed on the previously stored transformed data.

The surgical system 20002 may be in communication with a remote server 20009 that may be part of a cloud computing system 20008. In an example, the surgical system 20002 may be in communication with a remote server 20009 via an internet service provider's cable/FIOS networking node. In an example, a patient sensing system may be in direct communication with a remote server 20009. The surgical system 20002 and/or a component therein may communicate with the remote servers 20009 via a cellular transmission/reception point (TRP) or a base station using one or more of the following cellular protocols: GSM/GPRS/EDGE (2G), UMTS/HSPA (3G), long term evolution (LTE) or 4G, LTE-Advanced (LTE-A), new radio (NR) or 5G.

A surgical hub 20006 may have cooperative interactions with one of more means of displaying the image from the laparoscopic scope and information from one or more other smart devices and one or more sensing systems 20011. The surgical hub 20006 may interact with one or more sensing systems 20011, one or more smart devices, and multiple displays. The surgical hub 20006 may be configured to gather measurement data from the one or more sensing systems 20011 and send notifications or control messages to the one or more sensing systems 20011. The surgical hub 20006 may send and/or receive information including notification information to and/or from the human interface system 20012. The human interface system 20012 may include one or more human interface devices (HIDs). The surgical hub 20006 may send and/or receive notification information or control information to audio, display and/or control information to various devices that are in communication with the surgical hub.

For example, the sensing systems 20001 may include the wearable sensing system 20011 (which may include one or more HCP sensing systems and one or more patient sensing systems) and the environmental sensing system 20015 as discussed in FIG. 1A. The one or more sensing systems 20001 may measure data relating to various biomarkers. The one or more sensing systems 20001 may measure the biomarkers using one or more sensors, for example, photosensors (e.g., photodiodes, photoresistors), mechanical sensors (e.g., motion sensors), acoustic sensors, electrical sensors, electrochemical sensors, thermoelectric sensors, infrared sensors, etc. The one or more sensors may measure the biomarkers as described herein using one of more of the following sensing technologies: photoplethysmography, electrocardiography, electroencephalography, colorimetry, impedimentary, potentiometry, amperometry, etc.

Information from the biomarkers may be determined and/or used by the computer-implemented patient and the surgical system 20000, for example. The information from the biomarkers may be determined and/or used by the computer-implemented patient and the surgical system 20000 to improve said systems and/or to improve patient outcomes, for example. The one or more sensing systems 20001, biomarkers 20005, and physiological systems are described in more detail in U.S. application Ser. No. 17/156,287 (attorney docket number END9290USNP1), titled METHOD OF ADJUSTING A SURGICAL PARAMETER BASED ON BIOMARKER MEASUREMENTS, filed Jan. 22, 2021, the disclosure of which is herein incorporated by reference in its entirety.

FIG. 1B is a block diagram of a computer-implemented multi-tier surgical system. As illustrated in FIG. 1B, a computer-implemented multi-tier surgical system 40050 may include multiple tiers of systems, such as a surgical specific sub-network tier system 40052, an edge tier system 40054 that is associated with the surgical specific sub-network tier system 40052, and a cloud tier system 40056.

A surgical specific sub-network tier system 40052 may include a plurality of inter-connected surgical sub-systems. For example, the surgical sub-systems may be grouped by the type of surgical procedures and/or other departments in a medical facility or a hospital. For example, a medical facility or a hospital may include a plurality of surgical procedure specific departments, such as an emergency room (ER) department 40070, colorectal department 40078, bariatric department 40072, thoracic department 40066, and billing department 40068. Each of the surgical procedure specific departments may include one or more surgical sub-systems associated with an operating room (OR) and/or a healthcare care professional (HCP). For example, the colorectal department 40078 may include a set of surgical hubs (e.g., surgical hub 20006 as described in FIG. 1A). The surgical hubs may be designated for a respective HCP, such as HCP A, 40082 and HCP B, 40080. In an example, the colorectal department may include a group of surgical hubs that may be located in respective ORs, such as OR 1, 40074 and OR 2, 40076. The medical facility or the hospital may also include a billing department subsystem 40068. The billing department subsystem 40068 may store and/or manage billing data associated with a respective department, such as the ER department 40070, colorectal department 40078, bariatric department 40072, and/or thoracic department 40066.

An edge tier system 40054 may be associated with a medical facility or a hospital and may include one or more edge computing systems 40064, for example. An edge computing system 40064 may include a storage sub-system and a server sub-system. In an example, the edge computing system comprising an edge server and/or a storage unit may provide additional processing and/or storage services to a surgical hub that is part of one of the departmental ORs (e.g., OR1 and OR2 of the colorectal department).

The surgical specific sub-network tier system 40052 and the edge tier system 40054 may be located within a Health Insurance Portability and Accountability Act (HIPAA) boundary 40062. The surgical specific sub-network system 40052 and the edge tier system 40054 may be connected to the same local data network. The local data network may be a local data network of a medical facility or a hospital. The local data network may be within the HIPAA boundary. Because the surgical specific sub-network tier system 40052 and the edge tier system 40054 are located within the HIPAA boundary 40062, patient data between an edge computing system 40064 and a device located within one of the entities of the surgical specific sub-network tier system 40052 may flow without redaction and/or encryption. For example, patient data between an edge computing system 40064 and a surgical hub located in OR1 40074 of the colorectal department 40078 may flow without redaction and/or encryption.

The cloud tier system 40056 may include an enterprise cloud system 40060 and a public cloud system 40058. For example, the enterprise cloud system 40060 may be a cloud computing system 20008 that includes a remote cloud server sub-system and/or a remote cloud storage subsystem, as described in FIG. 1A. The enterprise cloud system 40060 may be managed by an organization, such as a private company.

The enterprise cloud system 40060 may be in communication with one or more entities (e.g., edge computing systems 40064, surgical hubs located in ORs (e.g., OR1 40074) of the various departments (e.g., colorectal department 40078)) that are located within the HIPAA boundary 40062.

The public cloud system 40058 may be operated by a cloud computing service provider. For example, the cloud computing service provider may provide storage services and/or computing services to a plurality of enterprise cloud systems (e.g., enterprise cloud system 40060).

FIG. 1C is a logical block diagram 40000 illustrating various communication planes in a surgical system. As illustrated in FIG. 1C, the communication planes between a controller 40002 and management applications 40014 and 40016 on one side and, the system modules and/or modular devices 40012 a through 40012 n on the other side, may use control plane 40008 and data plane 40010. In an example, in addition to the control plane 40008, a data plane may also exist between the system modules and/or modular devices 40012 a through 40012 n and the surgical hub. The data plane 40010 may provide data plane paths (e.g., redundant data plane paths) between the system modules and/or the modular devices 40012 a through 40012 n that are associated with one or more surgical hubs. A surgical hub or one of the surgical hubs (e.g., in case of a plurality of surgical hubs present in an operating room) may act as a controller 40002. In an example, the controller 40002 may be an edge computing system that may reside within a Health Insurance Portability and Accountability Act (HIPAA) boundary where the surgical system is located, for example, as illustrated in FIG. 1B. The controller 40002 may be in communication with an enterprise cloud system 40020. As illustrated in FIG. 1C, the enterprise cloud system 40020 may be located outside the HIPAA boundary 40018. Accordingly, the patient data flowing to and/or from the enterprise cloud system 40020 may be redacted and/or encrypted.

The controller 40002 may be configured to provide a northbound interface 40004 and a southbound interface 40006. The northbound interface 40004 may be used for providing a control plane 40008. The control plane 40008 may include one or more management applications 40014 and 40016 that may enable a user to configure and/or manage system modules and/or modular devices modular devices 40012 a through 40012 n associated with a surgical system. The management applications 40014 and 40016 may be used to obtain status of various system modules and/or the modular devices 40012 a through 40012 n.

The management applications 40014 and 40016 using the control plane may interact with the controller 40002, for example, using a set of application programming interface (API) calls. The management applications 40014 and 40016 may interact with the controller 40002 via a management protocol or an application layer protocol to configure and/or monitor the status of a system module and/or a modular device. The management protocols or the application layer protocols used to monitor the status and/or configure a system module or a modular device associated with a surgical system may include the simple network management protocol (SNMP), TELNET protocol, secure shell (SSH) protocol, network configuration protocol (NETCONF), etc.

SNMP or a similar protocol may be used to collect status information and/or send configuration related data (e.g., configuration related control programs) associated with system modules and/or modular devices to the controller. SNMP or a similar protocol may collect information by selecting devices associated with a surgical system from a central network management console using messages (e.g., SNMP messages). The messages may be sent and/or received at fixed or random intervals. The messages may include Get messages and Set messages. The Get messages or messages similar to the Get messages may be used for obtaining information from a system module or a modular device associated with a surgical system. The Set message or messages similar to the Set message may be used for changing a configuration associated with a system module or a modular device associated with a surgical system.

For example, the Get messages or similar messages may include the SNMP messages GetRequest, GetNextRequest, or GetBulkRequest. The Set messages may include SNMP SetRequest message. The GetRequest, GetNextRequest, GetBulkRequest messages or similar messages may be used by a configuration manager (e.g., an SNMP manager) running on the controller 40002. The configuration manager may be in communication with a communication agent (e.g., an SNMP agent) that may be a part of a system module and/or a modular device in a surgical system. The SNMP message SetRequest message or similar may be used by the communication manager on the controller 40002 to set the value of a parameter or an object instance in the communication agent on a system module and/or a modular device of a surgical system. In an example, SNMP modules, for example, may be used to establish communication path between system modules and/or modular devices associated with a surgical system.

Based on the query or configuration related messages received from a management application, such as management applications 40014 and 40016, the controller 40002 may generate configuration queries and/or configuration data for querying or configuring the system modules and/or the modular devices associated with the surgical hub or the surgical system. A surgical hub (e.g., the surgical hub 20006 shown in FIG. 1A) or an edge computing system (e.g., the edge computing system 40064 shown in FIG. 1B) may manage and/or control various system modules and/or modular devices 40012 a through 40012 n associated with a surgical system. For example, the northbound interface 40004 of the controller 40002 may be used for changing control interactions between one or more modules associated and/or devices associated with a surgical system. In an example, the controller 40002 may be used for establishing one or more communication data paths between a plurality of modules and/or devices associated with a surgical system. The controller 40002 may use its southbound interface 40006 to send the control programs comprising queries and/or configuration changes to the system modules and/or the modular devices of the surgical system.

The system modules and/or the modular devices 40012 a through 40012 n of a surgical system, or the communication agents that may be a part of the system modules and/or the modular devices, may send notification messages or traps to the controller 40002. The controller may forward the notification messages or traps via its northbound interface 40004 to the management application 40014 and 40016 for displaying on a display. In an example, the controller 40002 may send the notification to other system modules and/or modular devices 40012 a through 40012 n that are part of the surgical system.

The system modules and/or the modular devices 40012 a through 40012 n of a surgical system or the communication agents that are part of the system modules and/or the modular devices may send responses to the queries received from the controller 40002. For example, a communication agent that may be part of a system module or a modular device may send a response message in response to a Get or a Set message or messages similar to the Get or the Set messages received from the controller 40002. In an example, in response to a Get message or a similar message received from the controller 40002, the response message from the system module or the modular device 40012 a through 40012 n may include the data requested. In an example, in response to a Set message or a similar message received from a system module or a modular device 40012 a through 40012 n, the response message from the controller 40002 may include the newly set value as confirmation that the value has been set.

A trap or a notification message or a message similar to the trap or the notification message may be used by a system module or a modular device 40012 a through 40012 n to provide information about events associated with the system modules or the modular devices. For example, a trap or a notification message may be sent from a system module or a modular device 40012 a through 40012 n to the controller 40002 indicating a status of a communication interface (e.g., whether it available or unavailable for communication). The controller 40002 may send a receipt of the trap message back to the system module or the modular device 40012 a through 40012 n (e.g., to the agent on the system module or a modular device).

In an example, TELNET protocol may be used to provide a bidirectional interactive text-oriented communication facility between system modules and/or modular devices 40012 a through 40012 n and the controller 40002. TELNET protocol may be used to collect status information and/or send configuration data (e.g., control programs) from/to the controller 40002. TELNET may be used by one of the management applications 40014 or 40016 to establish a connection with the controller 40002 using the transmission control protocol port number 23.

In an example, SSH, a cryptographic encrypted protocol, may be used to allow remote login and to collect status information and/or send configuration data about system modules and/or modular devices 40012 a through 40012 n from/to the controller 40002. SSH may be used by one of the management applications 40014 or 40016 to establish an encrypted connection with the controller 40002 using the transmission control protocol port number 22.

In an example, NETCONF may be used to perform management functions by invoking remote procedure calls using, for example, <rpc>, <rpc-reply>, or <edit-config> operations. The <rpc> and <rpc-reply> procedure calls or similar procedure calls may be used for exchanging information from a system module and/or a modular device associated with a surgical system. The NETCONF <edit-config>operation or a similar operation may be used for configuring the system modules and/or the modular devices associated with the surgical system.

The controller 40002 may configure the system modules and/or modular device 40012 a through 40012 n to establish a data plane 40010. The data plane 40010 (e.g., also referred to as a user plane or a forwarding plane) may enable a communication data path between a plurality of system modules and/or modular device 40012 a through 40012 n. The data plane 40010 may be utilized by the system modules and/or the modular device 40012 a through 40012 n for communicating data flows of data between the system modules and/or modular devices associated with a surgical system. The data flows may be established using one or more dedicated communication interfaces between the system modules and/or the modular devices associated with one or more surgical hubs of a surgical system. In an example, the data flows may be established over one or more local area networks (LANs) and one or more wide area networks (WANs), such as the Internet.

In an example, the data plane 40010 may provide support for establishing a first and a second independent, disjointed, concurrent, and redundant communication path for data flow between the system modules and/or modular devices 40012 b and 40012 n. As illustrated in FIG. 1C. redundant communication paths may be established between system modules/modular devices 40012 b and 40012 n. The redundant communication paths may carry same/redundant data flows between the system modules and/or modular devices. In an example, when or if some of the data packets are dropped on one of the redundant communication paths due to problems with one of the communication interfaces on the system modules/modular devices 40012 b and 40012 n, the system modules and/or the modular devices may continue to send/receive at least one copy of the dropped data packets over the second communication path.

FIG. 2 shows an example of a surgical system 20002 in a surgical operating room. As illustrated in FIG. 2 , a patient is being operated on by one or more health care professionals (HCPs). The HCPs are being monitored by one or more HCP sensing systems 20020 worn by the HCPs. The HCPs and the environment surrounding the HCPs may also be monitored by one or more environmental sensing systems including, for example, a set of cameras 20021, a set of microphones 20022, and other sensors that may be deployed in the operating room. The HCP sensing systems 20020 and the environmental sensing systems may be in communication with a surgical hub 20006, which in turn may be in communication with one or more cloud servers 20009 of the cloud computing system 20008, as shown in FIG. 1A. The environmental sensing systems may be used for measuring one or more environmental attributes, for example, HCP position in the surgical theater, HCP movements, ambient noise in the surgical theater, temperature/humidity in the surgical theater, etc.

As illustrated in FIG. 2 , a primary display 20023 and one or more audio output devices (e.g., speakers 20019) are positioned in the sterile field to be visible to an operator at the operating table 20024. In addition, a visualization/notification tower 20026 is positioned outside the sterile field. The visualization/notification tower 20026 may include a first non-sterile human interactive device (HID) 20027 and a second non-sterile HID 20029, which may face away from each other. The HID may be a display or a display with a touchscreen allowing a human to interface directly with the HID. A human interface system, guided by the surgical hub 20006, may be configured to utilize the HIDs 20027, 20029, and 20023 to coordinate information flow to operators inside and outside the sterile field. In an example, the surgical hub 20006 may cause an HID (e.g., the primary HID 20023) to display a notification and/or information about the patient and/or a surgical procedure step. In an example, the surgical hub 20006 may prompt for and/or receive input from personnel in the sterile field or in the non-sterile area. In an example, the surgical hub 20006 may cause an HID to display a snapshot of a surgical site, as recorded by an imaging device 20030, on a non-sterile HID 20027 or 20029, while maintaining a live feed of the surgical site on the primary HID 20023. The snapshot on the non-sterile display 20027 or 20029 can permit a non-sterile operator to perform a diagnostic step relevant to the surgical procedure, for example.

In one aspect, the surgical hub 20006 may be configured to route a diagnostic input or feedback entered by a non-sterile operator at the visualization tower 20026 to the primary display 20023 within the sterile field, where it can be viewed by a sterile operator at the operating table. In one example, the input can be in the form of a modification to the snapshot displayed on the non-sterile display 20027 or 20029, which can be routed to the primary display 20023 by the surgical hub 20006.

Referring to FIG. 2 , a surgical instrument 20031 is being used in the surgical procedure as part of the surgical system 20002. The hub 20006 may be configured to coordinate information flow to a display of the surgical instrument 20031. For example, in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety. A diagnostic input or feedback entered by a non-sterile operator at the visualization tower 20026 can be routed by the hub 20006 to the surgical instrument display within the sterile field, where it can be viewed by the operator of the surgical instrument 20031. Example surgical instruments that are suitable for use with the surgical system 20002 are described under the heading “Surgical Instrument Hardware” and in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety, for example.

FIG. 2 illustrates an example of a surgical system 20002 being used to perform a surgical procedure on a patient who is lying down on an operating table 20024 in a surgical operating room 20035. A robotic system 20034 may be used in the surgical procedure as a part of the surgical system 20002. The robotic system 20034 may include a surgeon's console 20036, a patient side cart 20032 (surgical robot), and a surgical robotic hub 20033. The patient side cart 20032 can manipulate at least one removably coupled surgical tool 20037 through a minimally invasive incision in the body of the patient while the surgeon views the surgical site through the surgeon's console 20036. An image of the surgical site can be obtained by a medical imaging device 20030, which can be manipulated by the patient side cart 20032 to orient the imaging device 20030. The robotic hub 20033 can be used to process the images of the surgical site for subsequent display to the surgeon through the surgeon's console 20036.

Other types of robotic systems can be readily adapted for use with the surgical system 20002. Various examples of robotic systems and surgical tools that are suitable for use with the present disclosure are described in U.S. Patent Application Publication No. US 2019-0201137 A1 (U.S. patent application Ser. No. 16/209,407), titled METHOD OF ROBOTIC HUB COMMUNICATION, DETECTION, AND CONTROL, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety.

Various examples of cloud-based analytics that are performed by the cloud computing system 20008, and are suitable for use with the present disclosure, are described in U.S. Patent Application Publication No. US 2019-0206569 A1 (U.S. patent application Ser. No. 16/209,403), titled METHOD OF CLOUD BASED DATA ANALYTICS FOR USE WITH THE HUB, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety.

In various aspects, the imaging device 20030 may include at least one image sensor and one or more optical components. Suitable image sensors may include, but are not limited to, Charge-Coupled Device (CCD) sensors and Complementary Metal-Oxide Semiconductor (CMOS) sensors.

The optical components of the imaging device 20030 may include one or more illumination sources and/or one or more lenses. The one or more illumination sources may be directed to illuminate portions of the surgical field. The one or more image sensors may receive light reflected or refracted from the surgical field, including light reflected or refracted from tissue and/or surgical instruments.

The one or more illumination sources may be configured to radiate electromagnetic energy in the visible spectrum as well as the invisible spectrum. The visible spectrum, sometimes referred to as the optical spectrum or luminous spectrum, is the portion of the electromagnetic spectrum that is visible to (i.e., can be detected by) the human eye and may be referred to as visible light or simply light. A typical human eye will respond to wavelengths in air that range from about 380 nm to about 750 nm.

The invisible spectrum (e.g., the non-luminous spectrum) is the portion of the electromagnetic spectrum that lies below and above the visible spectrum (i.e., wavelengths below about 380 nm and above about 750 nm). The invisible spectrum is not detectable by the human eye. Wavelengths greater than about 750 nm are longer than the red visible spectrum, and they become invisible infrared (IR), microwave, and radio electromagnetic radiation. Wavelengths less than about 380 nm are shorter than the violet spectrum, and they become invisible ultraviolet, x-ray, and gamma ray electromagnetic radiation.

In various aspects, the imaging device 20030 is configured for use in a minimally invasive procedure. Examples of imaging devices suitable for use with the present disclosure include, but are not limited to, an arthroscope, angioscope, bronchoscope, choledochoscope, colonoscope, cytoscope, duodenoscope, enteroscope, esophagogastro-duodenoscope (gastroscope), endoscope, laryngoscope, nasopharyngo-neproscope, sigmoidoscope, thoracoscope, and ureteroscope.

The imaging device may employ multi-spectrum monitoring to discriminate topography and underlying structures. A multi-spectral image is one that captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or by the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, e.g., IR and ultraviolet. Spectral imaging can allow extraction of additional information that the human eye fails to capture with its receptors for red, green, and blue. The use of multi-spectral imaging is described in greater detail under the heading “Advanced Imaging Acquisition Module” in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety. Multi-spectrum monitoring can be a useful tool in relocating a surgical field after a surgical task is completed to perform one or more of the previously described tests on the treated tissue. It is axiomatic that strict sterilization of the operating room and surgical equipment is required during any surgery. The strict hygiene and sterilization conditions required in a “surgical theater,” i.e., an operating or treatment room, necessitate the highest possible sterility of all medical devices and equipment. Part of that sterilization process is the need to sterilize anything that comes in contact with the patient or penetrates the sterile field, including the imaging device 20030 and its attachments and components. It will be appreciated that the sterile field may be considered a specified area, such as within a tray or on a sterile towel, that is considered free of microorganisms, or the sterile field may be considered an area, immediately around a patient, who has been prepared for a surgical procedure. The sterile field may include the scrubbed team members, who are properly attired, and all furniture and fixtures in the area.

Wearable sensing system 20011 illustrated in FIG. 1A may include one or more sensing systems, for example, HCP sensing systems 20020 as shown in FIG. 2 . The HCP sensing systems 20020 may include sensing systems to monitor and detect a set of physical states and/or a set of physiological states of a healthcare personnel (HCP). An HCP may be a surgeon or one or more healthcare personnel assisting the surgeon or other healthcare service providers in general. In an example, a sensing system 20020 may measure a set of biomarkers to monitor the heart rate of an HCP. In an example, a sensing system 20020 worn on a surgeon's wrist (e.g., a watch or a wristband) may use an accelerometer to detect hand motion and/or shakes and determine the magnitude and frequency of tremors. The sensing system 20020 may send the measurement data associated with the set of biomarkers and the data associated with a physical state of the surgeon to the surgical hub 20006 for further processing. One or more environmental sensing devices may send environmental information to the surgical hub 20006. For example, the environmental sensing devices may include a camera 20021 for detecting hand/body position of an HCP. The environmental sensing devices may include microphones 20022 for measuring the ambient noise in the surgical theater. Other environmental sensing devices may include devices, for example, a thermometer to measure temperature and a hygrometer to measure humidity of the surroundings in the surgical theater, etc. The surgical hub 20006, alone or in communication with the cloud computing system, may use the surgeon biomarker measurement data and/or environmental sensing information to modify the control algorithms of hand-held instruments or the averaging delay of a robotic interface, for example, to minimize tremors. In an example, the HCP sensing systems 20020 may measure one or more surgeon biomarkers associated with an HCP and send the measurement data associated with the surgeon biomarkers to the surgical hub 20006. The HCP sensing systems 20020 may use one or more of the following RF protocols for communicating with the surgical hub 20006: Bluetooth, Bluetooth Low-Energy (BLE), Bluetooth Smart, Zigbee, Z-wave, IPv6 Low-power wireless Personal Area Network (6LoWPAN), Wi-Fi. The surgeon biomarkers may include one or more of the following: stress, heart rate, etc. The environmental measurements from the surgical theater may include ambient noise level associated with the surgeon or the patient, surgeon and/or staff movements, surgeon and/or staff attention level, etc.

The surgical hub 20006 may use the surgeon biomarker measurement data associated with an HCP to adaptively control one or more surgical instruments 20031. For example, the surgical hub 20006 may send a control program to a surgical instrument 20031 to control its actuators to limit or compensate for fatigue and use of fine motor skills. The surgical hub 20006 may send the control program based on situational awareness and/or the context on importance or criticality of a task. The control program may instruct the instrument to alter operation to provide more control when control is needed.

FIG. 3 shows an example surgical system 20002 with a surgical hub 20006 paired with a wearable sensing system 20011, an environmental sensing system 20015, a human interface system 20012, a robotic system 20013, and an intelligent instrument 20014. The hub 20006 includes a display 20048, an imaging module 20049, a generator module 20050, a communication module 20056, a processor module 20057, a storage array 20058, and an operating-room mapping module 20059. In certain aspects, as illustrated in FIG. 3 , the hub 20006 further includes a smoke evacuation module 20054 and/or a suction/irrigation module 20055. During a surgical procedure, energy application to tissue, for sealing and/or cutting, is generally associated with smoke evacuation, suction of excess fluid, and/or irrigation of the tissue. Fluid, power, and/or data lines from different sources are often entangled during the surgical procedure. Valuable time can be lost addressing this issue during a surgical procedure. Detangling the lines may necessitate disconnecting the lines from their respective modules, which may require resetting the modules. The hub modular enclosure 20060 offers a unified environment for managing the power, data, and fluid lines, which reduces the frequency of entanglement between such lines. Aspects of the present disclosure present a surgical hub 20006 for use in a surgical procedure that involves energy application to tissue at a surgical site. The surgical hub 20006 includes a hub enclosure 20060 and a combo generator module slidably receivable in a docking station of the hub enclosure 20060. The docking station includes data and power contacts. The combo generator module includes two or more of an ultrasonic energy generator component, a bipolar RF energy generator component, and a monopolar RF energy generator component that are housed in a single unit. In one aspect, the combo generator module also includes a smoke evacuation component, at least one energy delivery cable for connecting the combo generator module to a surgical instrument, at least one smoke evacuation component configured to evacuate smoke, fluid, and/or particulates generated by the application of therapeutic energy to the tissue, and a fluid line extending from the remote surgical site to the smoke evacuation component. In one aspect, the fluid line may be a first fluid line, and a second fluid line may extend from the remote surgical site to a suction and irrigation module 20055 slidably received in the hub enclosure 20060. In one aspect, the hub enclosure 20060 may include a fluid interface. Certain surgical procedures may require the application of more than one energy type to the tissue. One energy type may be more beneficial for cutting the tissue, while another different energy type may be more beneficial for sealing the tissue. For example, a bipolar generator can be used to seal the tissue while an ultrasonic generator can be used to cut the sealed tissue. Aspects of the present disclosure present a solution where a hub modular enclosure 20060 is configured to accommodate different generators and facilitate an interactive communication therebetween. One of the advantages of the hub modular enclosure 20060 is enabling the quick removal and/or replacement of various modules. Aspects of the present disclosure present a modular surgical enclosure for use in a surgical procedure that involves energy application to tissue. The modular surgical enclosure includes a first energy-generator module, configured to generate a first energy for application to the tissue, and a first docking station comprising a first docking port that includes first data and power contacts, wherein the first energy-generator module is slidably movable into an electrical engagement with the power and data contacts and wherein the first energy-generator module is slidably movable out of the electrical engagement with the first power and data contacts. Further to the above, the modular surgical enclosure also includes a second energy-generator module configured to generate a second energy, different than the first energy, for application to the tissue, and a second docking station comprising a second docking port that includes second data and power contacts, wherein the second energy generator module is slidably movable into an electrical engagement with the power and data contacts, and wherein the second energy-generator module is slidably movable out of the electrical engagement with the second power and data contacts. In addition, the modular surgical enclosure also includes a communication bus between the first docking port and the second docking port, configured to facilitate communication between the first energy-generator module and the second energy-generator module. Referring to FIG. 3 , aspects of the present disclosure are presented for a hub modular enclosure 20060 that allows the modular integration of a generator module 20050, a smoke evacuation module 20054, and a suction/irrigation module 20055. The hub modular enclosure 20060 further facilitates interactive communication between the modules 20059, 20054, and 20055. The generator module 20050 can be with integrated monopolar, bipolar, and ultrasonic components supported in a single housing unit slidably insertable into the hub modular enclosure 20060. The generator module 20050 can be configured to connect to a monopolar device 20051, a bipolar device 20052, and an ultrasonic device 20053. Alternatively, the generator module 20050 may comprise a series of monopolar, bipolar, and/or ultrasonic generator modules that interact through the hub modular enclosure 20060. The hub modular enclosure 20060 can be configured to facilitate the insertion of multiple generators and interactive communication between the generators docked into the hub modular enclosure 20060 so that the generators would act as a single generator.

FIG. 4 illustrates a surgical data network having a set of communication hubs configured to connect a set of sensing systems, environment sensing system(s), and a set of other modular devices located in one or more operating theaters of a healthcare facility, a patient recovery room, or a room in a healthcare facility specially equipped for surgical operations, to the cloud, in accordance with at least one aspect of the present disclosure.

As illustrated in FIG. 4 , a surgical hub system 20060 may include a modular communication hub 20065 that is configured to connect modular devices located in a healthcare facility to a cloud-based system (e.g., a cloud computing system 20064 that may include a remote server 20067 coupled to a remote storage 20068). The modular communication hub 20065 and the devices may be connected in a room in a healthcare facility specially equipped for surgical operations. In one aspect, the modular communication hub 20065 may include a network hub 20061 and/or a network switch 20062 in communication with a network router 20066. The modular communication hub 20065 may be coupled to a local computer system 20063 to provide local computer processing and data manipulation.

The computer system 20063 may comprise a processor and a network interface 20100. The processor may be coupled to a communication module, storage, memory, non-volatile memory, and input/output (I/O) interface via a system bus. The system bus can be any of several types of bus structure(s) including the memory bus or memory controller, a peripheral bus or external bus, and/or a local bus using any variety of available bus architectures including, but not limited to, 9-bit bus, Industrial Standard Architecture (ISA), Micro-Charmel Architecture (MSA), Extended ISA (EISA), Intelligent Drive Electronics (IDE), VESA Local Bus (VLB), Peripheral Component Interconnect (PCI), USB, Advanced Graphics Port (AGP), Personal Computer Memory Card International Association bus (PCMCIA), Small Computer Systems Interface (SCSI), or any other proprietary bus.

The processor may be any single-core or multicore processor such as those known under the trade name ARM Cortex by Texas Instruments. In one aspect, the processor may be an LM4F230H5QR ARM Cortex-M4F Processor Core, available from Texas Instruments, for example, comprising an on-chip memory of 256 KB single-cycle flash memory, or other non-volatile memory, up to 40 MHz, a prefetch buffer to improve performance above 40 MHz, a 32 KB single-cycle serial random access memory (SRAM), an internal read-only memory (ROM) loaded with StellarisWare® software, a 2 KB electrically erasable programmable read-only memory (EEPROM), and/or one or more pulse width modulation (PWM) modules, one or more quadrature encoder inputs (QEI) analogs, one or more 12-bit analog-to-digital converters (ADCs) with 12 analog input channels, details of which are available for the product datasheet.

In an example, the processor may comprise a safety controller comprising two controller-based families such as TMS570 and RM4x, known under the trade name Hercules ARM Cortex R4, also by Texas Instruments. The safety controller may be configured specifically for IEC 61508 and ISO 26262 safety critical applications, among others, to provide advanced integrated safety features while delivering scalable performance, connectivity, and memory options.

It is to be appreciated that the computer system 20063 may include software that acts as an intermediary between users and the basic computer resources described in a suitable operating environment. Such software may include an operating system. The operating system, which can be stored on the disk storage, may act to control and allocate resources of the computer system. System applications may take advantage of the management of resources by the operating system through program modules and program data stored either in the system memory or on the disk storage. It is to be appreciated that various components described herein can be implemented with various operating systems or combinations of operating systems.

A user may enter commands or information into the computer system 20063 through input device(s) coupled to the I/O interface. The input devices may include, but are not limited to, a pointing device such as a mouse, trackball, stylus, touch pad, keyboard, microphone, joystick, game pad, satellite dish, scanner, TV tuner card, digital camera, digital video camera, web camera, and the like. These and other input devices connect to the processor 20102 through the system bus via interface port(s). The interface port(s) include, for example, a serial port, a parallel port, a game port, and a USB. The output device(s) use some of the same types of ports as input device(s). Thus, for example, a USB port may be used to provide input to the computer system 20063 and to output information from the computer system 20063 to an output device. An output adapter may be provided to illustrate that there can be some output devices like monitors, displays, speakers, and printers, among other output devices that may require special adapters. The output adapters may include, by way of illustration and not limitation, video and sound cards that provide a means of connection between the output device and the system bus. It should be noted that other devices and/or systems of devices, such as remote computer(s), may provide both input and output capabilities.

The computer system 20063 can operate in a networked environment using logical connections to one or more remote computers, such as cloud computer(s), or local computers. The remote cloud computer(s) can be a personal computer, server, router, network PC, workstation, microprocessor-based appliance, peer device, or other common network node, and the like, and typically includes many or all of the elements described relative to the computer system. For purposes of brevity, only a memory storage device is illustrated with the remote computer(s). The remote computer(s) may be logically connected to the computer system through a network interface and then physically connected via a communication connection. The network interface may encompass communication networks such as local area networks (LANs) and wide area networks (WANs). LAN technologies may include Fiber Distributed Data Interface (FDDI), Copper Distributed Data Interface (CDDI), Ethernet/IEEE 802.3, Token Ring/IEEE 802.5, and the like. WAN technologies may include, but are not limited to, point-to-point links, circuit-switching networks like Integrated Services Digital Networks (ISDN) and variations thereon, packet-switching networks, and Digital Subscriber Lines (DSL).

In various examples, the computer system 20063 may comprise an image processor, image-processing engine, media processor, or any specialized digital signal processor (DSP) used for the processing of digital images. The image processor may employ parallel computing with single instruction, multiple data (SIMD) or multiple instruction, multiple data (MIMD) technologies to increase speed and efficiency. The digital image-processing engine can perform a range of tasks. The image processor may be a system on a chip with multicore processor architecture.

The communication connection(s) may refer to the hardware/software employed to connect the network interface to the bus. While the communication connection is shown for illustrative clarity inside the computer system 20063, it can also be external to the computer system 20063. The hardware/software necessary for connection to the network interface may include, for illustrative purposes only, internal and external technologies such as modems, including regular telephone-grade modems, cable modems, optical fiber modems, and DSL modems, ISDN adapters, and Ethernet cards. In some examples, the network interface may also be provided using an RF interface.

Surgical data network associated with the surgical hub system 20060 may be configured as passive, intelligent, or switching. A passive surgical data network serves as a conduit for the data, enabling it to go from one device (or segment) to another and to the cloud computing resources. An intelligent surgical data network includes additional features to enable the traffic passing through the surgical data network to be monitored and to configure each port in the network hub 20061 or network switch 20062. An intelligent surgical data network may be referred to as a manageable hub or switch. A switching hub reads the destination address of each packet and then forwards the packet to the correct port.

Modular devices 1 a-1 n located in the operating theater may be coupled to the modular communication hub 20065. The network hub 20061 and/or the network switch 20062 may be coupled to a network router 20066 to connect the devices 1 a-1 n to the cloud computing system 20064 or the local computer system 20063. Data associated with the devices 1 a-1 n may be transferred to cloud-based computers via the router for remote data processing and manipulation. Data associated with the devices 1 a-1 n may also be transferred to the local computer system 20063 for local data processing and manipulation. Modular devices 2 a-2 m located in the same operating theater also may be coupled to a network switch 20062. The network switch 20062 may be coupled to the network hub 20061 and/or the network router 20066 to connect the devices 2 a-2 m to the cloud 20064. Data associated with the devices 2 a-2 m may be transferred to the cloud computing system 20064 via the network router 20066 for data processing and manipulation. Data associated with the devices 2 a-2 m may also be transferred to the local computer system 20063 for local data processing and manipulation.

The wearable sensing system 20011 may include one or more sensing systems 20069. The sensing systems 20069 may include an HCP sensing system and/or a patient sensing system. The one or more sensing systems 20069 may be in communication with the computer system 20063 of a surgical hub system 20060 or the cloud server 20067 directly via one of the network routers 20066 or via a network hub 20061 or network switching 20062 that is in communication with the network routers 20066.

The sensing systems 20069 may be coupled to the network router 20066 to connect to the sensing systems 20069 to the local computer system 20063 and/or the cloud computing system 20064. Data associated with the sensing systems 20069 may be transferred to the cloud computing system 20064 via the network router 20066 for data processing and manipulation. Data associated with the sensing systems 20069 may also be transferred to the local computer system 20063 for local data processing and manipulation.

As illustrated in FIG. 4 , the surgical hub system 20060 may be expanded by interconnecting multiple network hubs 20061 and/or multiple network switches 20062 with multiple network routers 20066. The modular communication hub 20065 may be contained in a modular control tower configured to receive multiple devices 1 a-1 n/2 a-2 m. The local computer system 20063 also may be contained in a modular control tower. The modular communication hub 20065 may be connected to a display 20068 to display images obtained by some of the devices 1 a-1 n/2 a-2 m, for example during surgical procedures. In various aspects, the devices 1 a-1 n/2 a-2 m may include, for example, various modules such as an imaging module coupled to an endoscope, a generator module coupled to an energy-based surgical device, a smoke evacuation module, a suction/irrigation module, a communication module, a processor module, a storage array, a surgical device coupled to a display, and/or a non-contact sensor module, among other modular devices that may be connected to the modular communication hub 20065 of the surgical data network.

In one aspect, the surgical hub system 20060 illustrated in FIG. 4 may comprise a combination of network hub(s), network switch(es), and network router(s) connecting the devices 1 a-1 n/2 a-2 m or the sensing systems 20069 to the cloud-base system 20064. One or more of the devices 1 a-1 n/2 a-2 m or the sensing systems 20069 coupled to the network hub 20061 or network switch 20062 may collect data in real-time and transfer the data to cloud computers for data processing and manipulation. It will be appreciated that cloud computing relies on sharing computing resources rather than having local servers or personal devices to handle software applications. The word “cloud” may be used as a metaphor for “the Internet,” although the term is not limited as such. Accordingly, the term “cloud computing” may be used herein to refer to “a type of Internet-based computing,” where different services—such as servers, storage, and applications—are delivered to the modular communication hub 20065 and/or computer system 20063 located in the surgical theater (e.g., a fixed, mobile, temporary, or field operating room or space) and to devices connected to the modular communication hub 20065 and/or computer system 20063 through the Internet. The cloud infrastructure may be maintained by a cloud service provider. In this context, the cloud service provider may be the entity that coordinates the usage and control of the devices 1 a-1 n/2 a-2 m located in one or more operating theaters. The cloud computing services can perform a large number of calculations based on the data gathered by smart surgical instruments, robots, sensing systems, and other computerized devices located in the operating theater. The hub hardware enables multiple devices, sensing systems, and/or connections to be connected to a computer that communicates with the cloud computing resources and storage.

Applying cloud computer data processing techniques on the data collected by the devices 1 a-1 n/2 a-2 m, the surgical data network can provide improved surgical outcomes, reduced costs, and improved patient satisfaction. At least some of the devices 1 a-1 n/2 a-2 m may be employed to view tissue states to assess leaks or perfusion of sealed tissue after a tissue sealing and cutting procedure. At least some of the devices 1 a-1 n/2 a-2 m may be employed to identify pathology, such as the effects of diseases, using the cloud-based computing to examine data including images of samples of body tissue for diagnostic purposes. This may include localization and margin confirmation of tissue and phenotypes. At least some of the devices 1 a-1 n/2 a-2 m may be employed to identify anatomical structures of the body using a variety of sensors integrated with imaging devices and techniques such as overlaying images captured by multiple imaging devices. The data gathered by the devices 1 a-1 n/2 a-2 m, including image data, may be transferred to the cloud computing system 20064 or the local computer system 20063 or both for data processing and manipulation including image processing and manipulation. The data may be analyzed to improve surgical procedure outcomes by determining if further treatment, such as the application of endoscopic intervention, emerging technologies, a targeted radiation, targeted intervention, and precise robotics to tissue-specific sites and conditions, may be pursued. Such data analysis may further employ outcome analytics processing and using standardized approaches may provide beneficial feedback to either confirm surgical treatments and the behavior of the surgeon or suggest modifications to surgical treatments and the behavior of the surgeon.

Applying cloud computer data processing techniques on the measurement data collected by the sensing systems 20069, the surgical data network can provide improved surgical outcomes, improved recovery outcomes, reduced costs, and improved patient satisfaction. At least some of the sensing systems 20069 may be employed to assess physiological conditions of a surgeon operating on a patient or a patient being prepared for a surgical procedure or a patient recovering after a surgical procedure. The cloud-based computing system 20064 may be used to monitor biomarkers associated with a surgeon or a patient in real-time and to generate surgical plans based at least on measurement data gathered prior to a surgical procedure, provide control signals to the surgical instruments during a surgical procedure, and notify a patient of a complication during post-surgical period.

The operating theater devices 1 a-1 n may be connected to the modular communication hub 20065 over a wired channel or a wireless channel depending on the configuration of the devices 1 a-1 n to a network hub 20061. The network hub 20061 may be implemented, in one aspect, as a local network broadcast device that works on the physical layer of the Open System Interconnection (OSI) model. The network hub may provide connectivity to the devices 1 a-1 n located in the same operating theater network. The network hub 20061 may collect data in the form of packets and sends them to the router in half duplex mode. The network hub 20061 may not store any media access control/Internet Protocol (MAC/IP) to transfer the device data. Only one of the devices 1 a-1 n can send data at a time through the network hub 20061. The network hub 20061 may not have routing tables or intelligence regarding where to send information and broadcasts all network data across each connection and to a remote server 20067 of the cloud computing system 20064. The network hub 20061 can detect basic network errors such as collisions but having all information broadcast to multiple ports can be a security risk and cause bottlenecks.

The operating theater devices 2 a-2 m may be connected to a network switch 20062 over a wired channel or a wireless channel. The network switch 20062 works in the data link layer of the OSI model. The network switch 20062 may be a multicast device for connecting the devices 2 a-2 m located in the same operating theater to the network. The network switch 20062 may send data in the form of frames to the network router 20066 and may work in full duplex mode. Multiple devices 2 a-2 m can send data at the same time through the network switch 20062. The network switch 20062 stores and uses MAC addresses of the devices 2 a-2 m to transfer data.

The network hub 20061 and/or the network switch 20062 may be coupled to the network router 20066 for connection to the cloud computing system 20064. The network router 20066 works in the network layer of the OSI model. The network router 20066 creates a route for transmitting data packets received from the network hub 20061 and/or network switch 20062 to cloud-based computer resources for further processing and manipulation of the data collected by any one of or all the devices 1 a-1 n/2 a-2 m and wearable sensing system 20011. The network router 20066 may be employed to connect two or more different networks located in different locations, such as, for example, different operating theaters of the same healthcare facility or different networks located in different operating theaters of different healthcare facilities. The network router 20066 may send data in the form of packets to the cloud computing system 20064 and works in full duplex mode. Multiple devices can send data at the same time. The network router 20066 may use IP addresses to transfer data.

In an example, the network hub 20061 may be implemented as a USB hub, which allows multiple USB devices to be connected to a host computer. The USB hub may expand a single USB port into several tiers so that there are more ports available to connect devices to the host system computer. The network hub 20061 may include wired or wireless capabilities to receive information over a wired channel or a wireless channel. In one aspect, a wireless USB short-range, high-bandwidth wireless radio communication protocol may be employed for communication between the devices 1 a-1 n and devices 2 a-2 m located in the operating theater.

In examples, the operating theater devices 1 a-1 n/2 a-2 m and/or the sensing systems 20069 may communicate to the modular communication hub 20065 via Bluetooth wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices and building personal area networks (PANs). The operating theater devices 1 a-1 n/2 a-2 m and/or the sensing systems 20069 may communicate to the modular communication hub 20065 via a number of wireless or wired communication standards or protocols, including but not limited to Bluetooth, Low-Energy Bluetooth, near-field communication (NFC), Wi-Fi (IEEE 802.11 family), WiMAX (IEEE 802.16 family), IEEE 802.20, new radio (NR), long-term evolution (LTE), and Ev-DO, HSPA+, HSDPA+, HSUPA+, EDGE, GSM, GPRS, CDMA, TDMA, DECT, and Ethernet derivatives thereof, as well as any other wireless and wired protocols that are designated as 3G, 4G, 5G, and beyond. The computing module may include a plurality of communication modules. For instance, a first communication module may be dedicated to shorter-range wireless communications such as Wi-Fi and Bluetooth Low-Energy Bluetooth, Bluetooth Smart, and a second communication module may be dedicated to longer-range wireless communications such as GPS, EDGE, GPRS, CDMA, WiMAX, LTE, Ev-DO, HSPA+, HSDPA+, HSUPA+, EDGE, GSM, GPRS, CDMA, TDMA, and others.

The modular communication hub 20065 may serve as a central connection for one or more of the operating theater devices 1 a-1 n/2 a-2 m and/or the sensing systems 20069 and may handle a data type known as frames. Frames may carry the data generated by the devices 1 a-1 n/2 a-2 m and/or the sensing systems 20069. When a frame is received by the modular communication hub 20065, it may be amplified and/or sent to the network router 20066, which may transfer the data to the cloud computing system 20064 or the local computer system 20063 by using a number of wireless or wired communication standards or protocols, as described herein.

The modular communication hub 20065 can be used as a standalone device or be connected to compatible network hubs 20061 and network switches 20062 to form a larger network. The modular communication hub 20065 can be generally easy to install, configure, and maintain, making it a good option for networking the operating theater devices 1 a-1 n/2 a-2 m.

The non-contact sensor module 20096 may measure the dimensions of the operating theater and generate a map of the surgical theater using, ultrasonic, laser-type, and/or the like, non-contact measurement devices. Other distance sensors can be employed to determine the bounds of an operating room. An ultrasound-based non-contact sensor module may scan the operating theater by transmitting a burst of ultrasound and receiving the echo when it bounces off the perimeter walls of an operating theater as described under the heading “Surgical Hub Spatial Awareness Within an Operating Room” in U.S. Provisional patent application Ser. No. 62/611,341, titled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, which is herein incorporated by reference in its entirety. The sensor module may be configured to determine the size of the operating theater and to adjust Bluetooth-pairing distance limits. A laser-based non-contact sensor module may scan the operating theater by transmitting laser light pulses, receiving laser light pulses that bounce off the perimeter walls of the operating theater, and comparing the phase of the transmitted pulse to the received pulse to determine the size of the operating theater and to adjust Bluetooth pairing distance limits, for example.

The modular control 20085 may also be in communication with one or more sensing systems 20069 and an environmental sensing system 20015. The sensing systems 20069 may be connected to the modular control 20085 either directly via a router or via the communication module 20097.

For example, the surgical instrument may include any of a powered stapler, a powered stapler generator, an energy device, an advanced energy device, an advanced energy jaw device, an endocutter clamp, an energy device generator, an in-operating-room imaging system, a smoke evacuator, a suction-irrigation device, an insufflation system, or the like. The system 20220 may comprise a control circuit. The control circuit may include a microcontroller 20221 comprising a processor 20222 and a memory 20223. One or more of sensors 20225, 20226, 20227, for example, provide real-time feedback to the processor 20222. A motor 20230, driven by a motor driver 20229, operably couples a longitudinally movable displacement member to drive the I-beam knife element. A tracking system 20228 may be configured to determine the position of the longitudinally movable displacement member. The position information may be provided to the processor 20222, which can be programmed or configured to determine the position of the longitudinally movable drive member as well as the position of a firing member, firing bar, and I-beam knife element. Additional motors may be provided at the tool driver interface to control I-beam firing, closure tube travel, shaft rotation, and articulation. A display 20224 may display a variety of operating conditions of the instruments and may include touch screen functionality for data input. Information displayed on the display 20224 may be overlaid with images acquired via endoscopic imaging modules.

The microcontroller 20221 may be any single-core or multicore processor such as those known under the trade name ARM Cortex by Texas Instruments. In one aspect, the main microcontroller 20221 may be an LM4F230H5QR ARM Cortex-M4F Processor Core, available from Texas Instruments, for example, comprising an on-chip memory of 256 KB single-cycle flash memory, or other non-volatile memory, up to 40 MHz, a prefetch buffer to improve performance above 40 MHz, a 32 KB single-cycle SRAM, and internal ROM loaded with StellarisWare® software, a 2 KB EEPROM, one or more PWM modules, one or more QEI analogs, and/or one or more 12-bit ADCs with 12 analog input channels, details of which are available for the product datasheet.

The microcontroller 20221 may comprise a safety controller comprising two controller-based families such as TMS570 and RM4x, known under the trade name Hercules ARM Cortex R4, also by Texas Instruments. The safety controller may be configured specifically for IEC 61508 and ISO 26262 safety critical applications, among others, to provide advanced integrated safety features while delivering scalable performance, connectivity, and memory options.

The microcontroller 20221 may be programmed to perform various functions such as precise control over the speed and position of the knife and articulation systems. In one aspect, the microcontroller 20221 may include a processor 20222 and a memory 20223. The electric motor 20230 may be a brushed direct current (DC) motor with a gearbox and mechanical links to an articulation or knife system. In one aspect, a motor driver 20229 may be an A3941 available from Allegro Microsystems, Inc. Other motor drivers may be readily substituted for use in the tracking system 20228 comprising an absolute positioning system. A detailed description of an absolute positioning system is described in U.S. Patent Application Publication No. 2017/0296213, titled SYSTEMS AND METHODS FOR CONTROLLING A SURGICAL STAPLING AND CUTTING INSTRUMENT, which published on Oct. 19, 2017, which is herein incorporated by reference in its entirety.

The microcontroller 20221 may be programmed to provide precise control over the speed and position of displacement members and articulation systems. The microcontroller 20221 may be configured to compute a response in the software of the microcontroller 20221. The computed response may be compared to a measured response of the actual system to obtain an “observed” response, which is used for actual feedback decisions. The observed response may be a favorable, tuned value that balances the smooth, continuous nature of the simulated response with the measured response, which can detect outside influences on the system.

The motor 20230 may be controlled by the motor driver 20229 and can be employed by the firing system of the surgical instrument or tool. In various forms, the motor 20230 may be a brushed DC driving motor having a maximum rotational speed of approximately 25,000 RPM. In some examples, the motor 20230 may include a brushless motor, a cordless motor, a synchronous motor, a stepper motor, or any other suitable electric motor. The motor driver 20229 may comprise an H-bridge driver comprising field-effect transistors (FETs), for example. The motor 20230 can be powered by a power assembly releasably mounted to the handle assembly or tool housing for supplying control power to the surgical instrument or tool. The power assembly may comprise a battery which may include a number of battery cells connected in series that can be used as the power source to power the surgical instrument or tool. In certain circumstances, the battery cells of the power assembly may be replaceable and/or rechargeable. In at least one example, the battery cells can be lithium-ion batteries which can be couplable to and separable from the power assembly.

The motor driver 20229 may be an A3941 available from Allegro Microsystems, Inc. A3941 may be a full-bridge controller for use with external N-channel power metal-oxide semiconductor field-effect transistors (MOSFETs) specifically designed for inductive loads, such as brush DC motors. The driver 20229 may comprise a unique charge pump regulator that can provide full (>10 V) gate drive for battery voltages down to 7 V and can allow the A3941 to operate with a reduced gate drive, down to 5.5 V. A bootstrap capacitor may be employed to provide the above battery supply voltage required for N-channel MOSFETs. An internal charge pump for the high-side drive may allow DC (100% duty cycle) operation. The full bridge can be driven in fast or slow decay modes using diode or synchronous rectification. In the slow decay mode, current recirculation can be through the high-side or the low-side FETs. The power FETs may be protected from shoot-through by resistor-adjustable dead time. Integrated diagnostics provide indications of undervoltage, overtemperature, and power bridge faults and can be configured to protect the power MOSFETs under most short circuit conditions. Other motor drivers may be readily substituted for use in the tracking system 20228 comprising an absolute positioning system.

The tracking system 20228 may comprise a controlled motor drive circuit arrangement comprising a position sensor 20225 according to one aspect of this disclosure. The position sensor 20225 for an absolute positioning system may provide a unique position signal corresponding to the location of a displacement member. In some examples, the displacement member may represent a longitudinally movable drive member comprising a rack of drive teeth for meshing engagement with a corresponding drive gear of a gear reducer assembly. In some examples, the displacement member may represent the firing member, which could be adapted and configured to include a rack of drive teeth. In some examples, the displacement member may represent a firing bar or the I-beam, each of which can be adapted and configured to include a rack of drive teeth. Accordingly, as used herein, the term displacement member can be used generically to refer to any movable member of the surgical instrument or tool such as the drive member, the firing member, the firing bar, the I-beam, or any element that can be displaced. In one aspect, the longitudinally movable drive member can be coupled to the firing member, the firing bar, and the I-beam. Accordingly, the absolute positioning system can, in effect, track the linear displacement of the I-beam by tracking the linear displacement of the longitudinally movable drive member. In various aspects, the displacement member may be coupled to any position sensor 20225 suitable for measuring linear displacement. Thus, the longitudinally movable drive member, the firing member, the firing bar, or the I-beam, or combinations thereof, may be coupled to any suitable linear displacement sensor. Linear displacement sensors may include contact or non-contact displacement sensors. Linear displacement sensors may comprise linear variable differential transformers (LVDT), differential variable reluctance transducers (DVRT), a slide potentiometer, a magnetic sensing system comprising a movable magnet and a series of linearly arranged Hall effect sensors, a magnetic sensing system comprising a fixed magnet and a series of movable, linearly arranged Hall effect sensors, an optical sensing system comprising a movable light source and a series of linearly arranged photo diodes or photo detectors, an optical sensing system comprising a fixed light source and a series of movable linearly, arranged photodiodes or photodetectors, or any combination thereof.

The electric motor 20230 can include a rotatable shaft that operably interfaces with a gear assembly that is mounted in meshing engagement with a set, or rack, of drive teeth on the displacement member. A sensor element may be operably coupled to a gear assembly such that a single revolution of the position sensor 20225 element corresponds to some linear longitudinal translation of the displacement member. An arrangement of gearing and sensors can be connected to the linear actuator, via a rack and pinion arrangement, or a rotary actuator, via a spur gear or other connection. A power source may supply power to the absolute positioning system and an output indicator may display the output of the absolute positioning system. The displacement member may represent the longitudinally movable drive member comprising a rack of drive teeth formed thereon for meshing engagement with a corresponding drive gear of the gear reducer assembly. The displacement member may represent the longitudinally movable firing member, firing bar, I-beam, or combinations thereof.

A single revolution of the sensor element associated with the position sensor 20225 may be equivalent to a longitudinal linear displacement d1 of the displacement member, where d1 is the longitudinal linear distance that the displacement member moves from point “a” to point “b” after a single revolution of the sensor element coupled to the displacement member. The sensor arrangement may be connected via a gear reduction that results in the position sensor 20225 completing one or more revolutions for the full stroke of the displacement member. The position sensor 20225 may complete multiple revolutions for the full stroke of the displacement member.

A series of switches, where n is an integer greater than one, may be employed alone or in combination with a gear reduction to provide a unique position signal for more than one revolution of the position sensor 20225. The state of the switches may be fed back to the microcontroller 20221 that applies logic to determine a unique position signal corresponding to the longitudinal linear displacement d1+d2+ do of the displacement member. The output of the position sensor 20225 is provided to the microcontroller 20221. The position sensor 20225 of the sensor arrangement may comprise a magnetic sensor, an analog rotary sensor like a potentiometer, or an array of analog Hall-effect elements, which output a unique combination of position signals or values.

The position sensor 20225 may comprise any number of magnetic sensing elements, such as, for example, magnetic sensors classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors may encompass many aspects of physics and electronics. The technologies used for magnetic field sensing may include search coil, fluxgate, optically pumped, nuclear precession, SQUID, Hall-effect, anisotropic magnetoresistance, giant magnetoresistance, magnetic tunnel junctions, giant magnetoimpedance, magnetostrictive/piezoelectric composites, magnetodiode, magnetotransistor, fiber-optic, magneto-optic, and microelectromechanical systems-based magnetic sensors, among others.

The position sensor 20225 for the tracking system 20228 comprising an absolute positioning system may comprise a magnetic rotary absolute positioning system. The position sensor 20225 may be implemented as an AS5055EQFT single-chip magnetic rotary position sensor available from Austria Microsystems, AG. The position sensor 20225 is interfaced with the microcontroller 20221 to provide an absolute positioning system. The position sensor 20225 may be a low-voltage and low-power component and may include four Hall-effect elements in an area of the position sensor 20225 that may be located above a magnet. A high-resolution ADC and a smart power management controller may also be provided on the chip. A coordinate rotation digital computer (CORDIC) processor, also known as the digit-by-digit method and Volder's algorithm, may be provided to implement a simple and efficient algorithm to calculate hyperbolic and trigonometric functions that require only addition, subtraction, bit-shift, and table lookup operations. The angle position, alarm bits, and magnetic field information may be transmitted over a standard serial communication interface, such as a serial peripheral interface (SPI) interface, to the microcontroller 20221. The position sensor 20225 may provide 12 or 14 bits of resolution. The position sensor 20225 may be an AS5055 chip provided in a small QFN 16-pin 4×4×0.85 mm package.

The tracking system 20228 comprising an absolute positioning system may comprise and/or be programmed to implement a feedback controller, such as a PID, state feedback, and adaptive controller. A power source converts the signal from the feedback controller into a physical input to the system: in this case the voltage. Other examples include a PWM of the voltage, current, and force. Other sensor(s) may be provided to measure physical parameters of the physical system in addition to the position measured by the position sensor 20225. In some aspects, the other sensor(s) can include sensor arrangements such as those described in U.S. Pat. No. 9,345,481, titled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, which issued on May 24, 2016, which is herein incorporated by reference in its entirety; U.S. Patent Application Publication No. 2014/0263552, titled STAPLE CARTRIDGE TISSUE THICKNESS SENSOR SYSTEM, which published on Sep. 18, 2014, which is herein incorporated by reference in its entirety; and U.S. patent application Ser. No. 15/628,175, titled TECHNIQUES FOR ADAPTIVE CONTROL OF MOTOR VELOCITY OF A SURGICAL STAPLING AND CUTTING INSTRUMENT, filed Jun. 20, 2017, which is herein incorporated by reference in its entirety. In a digital signal processing system, an absolute positioning system is coupled to a digital data acquisition system where the output of the absolute positioning system will have a finite resolution and sampling frequency. The absolute positioning system may comprise a compare-and-combine circuit to combine a computed response with a measured response using algorithms, such as a weighted average and a theoretical control loop, that drive the computed response towards the measured response. The computed response of the physical system may take into account properties like mass, inertia, viscous friction, inductance resistance, etc., to predict what the states and outputs of the physical system will be by knowing the input.

The absolute positioning system may provide an absolute position of the displacement member upon power-up of the instrument, without retracting or advancing the displacement member to a reset (zero or home) position as may be required with conventional rotary encoders that merely count the number of steps forwards or backwards that the motor 20230 has taken to infer the position of a device actuator, drive bar, knife, or the like.

A sensor 20226, such as, for example, a strain gauge or a micro-strain gauge, may be configured to measure one or more parameters of the end effector, such as, for example, the amplitude of the strain exerted on the anvil during a clamping operation, which can be indicative of the closure forces applied to the anvil. The measured strain may be converted to a digital signal and provided to the processor 20222. Alternatively, or in addition to the sensor 20226, a sensor 20227, such as, for example, a load sensor, can measure the closure force applied by the closure drive system to the anvil. The sensor 20227, such as, for example, a load sensor, can measure the firing force applied to an I-beam in a firing stroke of the surgical instrument or tool. The I-beam is configured to engage a wedge sled, which is configured to upwardly cam staple drivers to force out staples into deforming contact with an anvil. The I-beam also may include a sharpened cutting edge that can be used to sever tissue as the I-beam is advanced distally by the firing bar. Alternatively, a current sensor 20231 can be employed to measure the current drawn by the motor 20230. The force required to advance the firing member can correspond to the current drawn by the motor 20230, for example. The measured force may be converted to a digital signal and provided to the processor 20222.

For example, the strain gauge sensor 20226 can be used to measure the force applied to the tissue by the end effector. A strain gauge can be coupled to the end effector to measure the force on the tissue being treated by the end effector. A system for measuring forces applied to the tissue grasped by the end effector may comprise a strain gauge sensor 20226, such as, for example, a micro-strain gauge, that can be configured to measure one or more parameters of the end effector, for example. In one aspect, the strain gauge sensor 20226 can measure the amplitude or magnitude of the strain exerted on a jaw member of an end effector during a clamping operation, which can be indicative of the tissue compression. The measured strain can be converted to a digital signal and provided to a processor 20222 of the microcontroller 20221. A load sensor 20227 can measure the force used to operate the knife element, for example, to cut the tissue captured between the anvil and the staple cartridge. A magnetic field sensor can be employed to measure the thickness of the captured tissue. The measurement of the magnetic field sensor also may be converted to a digital signal and provided to the processor 20222.

The measurements of the tissue compression, the tissue thickness, and/or the force required to close the end effector on the tissue, as respectively measured by the sensors 20226, 20227, can be used by the microcontroller 20221 to characterize the selected position of the firing member and/or the corresponding value of the speed of the firing member. In one instance, a memory 20223 may store a technique, an equation, and/or a lookup table which can be employed by the microcontroller 20221 in the assessment.

The control system 20220 of the surgical instrument or tool also may comprise wired or wireless communication circuits to communicate with the modular communication hub 20065 as shown in FIG. 5 .

FIG. 7 illustrates an example surgical system 20280 in accordance with the present disclosure and may include a surgical instrument 20282 that can be in communication with a console 20294 or a portable device 20296 through a local area network 20292 and/or a cloud network 20293 via a wired and/or wireless connection.

The adapter 20285 releasably couples to the handle 20297 and the loading unit 20287 releasably couples to the adapter 20285 such that the adapter 20285 transmits a force from a drive shaft to the loading unit 20287. The adapter 20285 or the loading unit 20287 may include a force gauge (not explicitly shown) disposed therein to measure a force exerted on the loading unit 20287. The loading unit 20287 may include an end effector 20289 having a first jaw 20291 and a second jaw 20290. The loading unit 20287 may be an in-situ loaded or multi-firing loading unit (MFLU) that allows a clinician to fire a plurality of fasteners multiple times without requiring the loading unit 20287 to be removed from a surgical site to reload the loading unit 20287.

The first and second jaws 20291, 20290 may be configured to clamp tissue therebetween, fire fasteners through the clamped tissue, and sever the clamped tissue. The first jaw 20291 may be configured to fire at least one fastener a plurality of times or may be configured to include a replaceable multi-fire fastener cartridge including a plurality of fasteners (e.g., staples, clips, etc.) that may be fired more than one time prior to being replaced. The second jaw 20290 may include an anvil that deforms or otherwise secures the fasteners, as the fasteners are ejected from the multi-fire fastener cartridge.

The handle 20297 may include a motor that is coupled to the drive shaft to affect rotation of the drive shaft. The handle 20297 may include a control interface to selectively activate the motor. The control interface may include buttons, switches, levers, sliders, touchscreens, and any other suitable input mechanisms or user interfaces, which can be engaged by a clinician to activate the motor.

The control interface of the handle 20297 may be in communication with a controller 20298 of the handle 20297 to selectively activate the motor to affect rotation of the drive shafts. The controller 20298 may be disposed within the handle 20297 and may be configured to receive input from the control interface and adapter data from the adapter 20285 or loading unit data from the loading unit 20287. The controller 20298 may analyze the input from the control interface and the data received from the adapter 20285 and/or loading unit 20287 to selectively activate the motor. The handle 20297 may also include a display that is viewable by a clinician during use of the handle 20297. The display may be configured to display portions of the adapter or loading unit data before, during, or after firing of the instrument 20282.

The adapter 20285 may include an adapter identification device 20284 disposed therein and the loading unit 20287 may include a loading unit identification device 20288 disposed therein. The adapter identification device 20284 may be in communication with the controller 20298, and the loading unit identification device 20288 may be in communication with the controller 20298. It will be appreciated that the loading unit identification device 20288 may be in communication with the adapter identification device 20284, which relays or passes communication from the loading unit identification device 20288 to the controller 20298.

The adapter 20285 may also include a plurality of sensors 20286 (one shown) disposed thereabout to detect various conditions of the adapter 20285 or of the environment (e.g., if the adapter 20285 is connected to a loading unit, if the adapter 20285 is connected to a handle, if the drive shafts are rotating, the torque of the drive shafts, the strain of the drive shafts, the temperature within the adapter 20285, a number of firings of the adapter 20285, a peak force of the adapter 20285 during firing, a total amount of force applied to the adapter 20285, a peak retraction force of the adapter 20285, a number of pauses of the adapter 20285 during firing, etc.). The plurality of sensors 20286 may provide an input to the adapter identification device 20284 in the form of data signals. The data signals of the plurality of sensors 20286 may be stored within or be used to update the adapter data stored within the adapter identification device 20284. The data signals of the plurality of sensors 20286 may be analog or digital. The plurality of sensors 20286 may include a force gauge to measure a force exerted on the loading unit 20287 during firing.

The handle 20297 and the adapter 20285 can be configured to interconnect the adapter identification device 20284 and the loading unit identification device 20288 with the controller 20298 via an electrical interface. The electrical interface may be a direct electrical interface (i.e., include electrical contacts that engage one another to transmit energy and signals therebetween). Additionally, or alternatively, the electrical interface may be a non-contact electrical interface to wirelessly transmit energy and signals therebetween (e.g., inductively transfer). It is also contemplated that the adapter identification device 20284 and the controller 20298 may be in wireless communication with one another via a wireless connection separate from the electrical interface.

The handle 20297 may include a transceiver 20283 that is configured to transmit instrument data from the controller 20298 to other components of the system 20280 (e.g., the LAN 20292, the cloud 20293, the console 20294, or the portable device 20296). The controller 20298 may also transmit instrument data and/or measurement data associated with one or more sensors 20286 to a surgical hub. The transceiver 20283 may receive data (e.g., cartridge data, loading unit data, adapter data, or other notifications) from the surgical hub 20270. The transceiver 20283 may receive data (e.g., cartridge data, loading unit data, or adapter data) from the other components of the system 20280. For example, the controller 20298 may transmit instrument data including a serial number of an attached adapter (e.g., adapter 20285) attached to the handle 20297, a serial number of a loading unit (e.g., loading unit 20287) attached to the adapter 20285, and a serial number of a multi-fire fastener cartridge loaded into the loading unit to the console 20294. Thereafter, the console 20294 may transmit data (e.g., cartridge data, loading unit data, or adapter data) associated with the attached cartridge, loading unit, and adapter, respectively, back to the controller 20298. The controller 20298 can display messages on the local instrument display or transmit the message, via transceiver 20283, to the console 20294 or the portable device 20296 to display the message on the display 20295 or portable device screen, respectively.

FIG. 8 illustrates a diagram of a situationally aware surgical system 5100, in accordance with at least one aspect of the present disclosure. The data sources 5126 may include, for example, the modular devices 5102 (which can include sensors configured to detect parameters associated with the patient, HCPs and environment and/or the modular device itself), databases 5122 (e.g., an EMR database containing patient records), patient monitoring devices 5124 (e.g., a blood pressure (BP) monitor and an electrocardiography (EKG) monitor), HCP monitoring devices 35510, and/or environment monitoring devices 35512. The surgical hub 5104 can be configured to derive the contextual information pertaining to the surgical procedure from the data based upon, for example, the particular combination(s) of received data or the particular order in which the data is received from the data sources 5126. The contextual information inferred from the received data can include, for example, the type of surgical procedure being performed, the particular step of the surgical procedure that the surgeon is performing, the type of tissue being operated on, or the body cavity that is the subject of the procedure. This ability by some aspects of the surgical hub 5104 to derive or infer information related to the surgical procedure from received data can be referred to as “situational awareness.” For example, the surgical hub 5104 can incorporate a situational awareness system, which is the hardware and/or programming associated with the surgical hub 5104 that derives contextual information pertaining to the surgical procedure from the received data and/or a surgical plan information received from the edge computing system 35514 or an enterprise cloud server 35516.

The situational awareness system of the surgical hub 5104 can be configured to derive the contextual information from the data received from the data sources 5126 in a variety of different ways. For example, the situational awareness system can include a pattern recognition system, or machine learning system (e.g., an artificial neural network), that has been trained on training data to correlate various inputs (e.g., data from database(s) 5122, patient monitoring devices 5124, modular devices 5102, HCP monitoring devices 35510, and/or environment monitoring devices 35512) to corresponding contextual information regarding a surgical procedure. A machine learning system can be trained to accurately derive contextual information regarding a surgical procedure from the provided inputs. In examples, the situational awareness system can include a lookup table storing pre-characterized contextual information regarding a surgical procedure in association with one or more inputs (or ranges of inputs) corresponding to the contextual information. In response to a query with one or more inputs, the lookup table can return the corresponding contextual information for the situational awareness system for controlling the modular devices 5102. In examples, the contextual information received by the situational awareness system of the surgical hub 5104 can be associated with a particular control adjustment or set of control adjustments for one or more modular devices 5102. In examples, the situational awareness system can include a further machine learning system, lookup table, or other such system, which generates or retrieves one or more control adjustments for one or more modular devices 5102 when provided the contextual information as input.

A surgical hub 5104 incorporating a situational awareness system can provide a number of benefits for the surgical system 5100. One benefit may include improving the interpretation of sensed and collected data, which would in turn improve the processing accuracy and/or the usage of the data during the course of a surgical procedure. To return to a previous example, a situationally aware surgical hub 5104 could determine what type of tissue was being operated on; therefore, when an unexpectedly high force to close the surgical instrument's end effector is detected, the situationally aware surgical hub 5104 could correctly ramp up or ramp down the motor of the surgical instrument for the type of tissue.

The type of tissue being operated can affect the adjustments that are made to the compression rate and load thresholds of a surgical stapling and cutting instrument for a particular tissue gap measurement. A situationally aware surgical hub 5104 could infer whether a surgical procedure being performed is a thoracic or an abdominal procedure, allowing the surgical hub 5104 to determine whether the tissue clamped by an end effector of the surgical stapling and cutting instrument is lung (for a thoracic procedure) or stomach (for an abdominal procedure) tissue. The surgical hub 5104 could then adjust the compression rate and load thresholds of the surgical stapling and cutting instrument appropriately for the type of tissue.

The type of body cavity being operated in during an insufflation procedure can affect the function of a smoke evacuator. A situationally aware surgical hub 5104 could determine whether the surgical site is under pressure (by determining that the surgical procedure is utilizing insufflation) and determine the procedure type. As a procedure type can be generally performed in a specific body cavity, the surgical hub 5104 could then control the motor rate of the smoke evacuator appropriately for the body cavity being operated in. Thus, a situationally aware surgical hub 5104 could provide a consistent amount of smoke evacuation for both thoracic and abdominal procedures.

The type of procedure being performed can affect the optimal energy level for an ultrasonic surgical instrument or radio frequency (RF) electrosurgical instrument to operate at. Arthroscopic procedures, for example, may require higher energy levels because the end effector of the ultrasonic surgical instrument or RF electrosurgical instrument is immersed in fluid. A situationally aware surgical hub 5104 could determine whether the surgical procedure is an arthroscopic procedure. The surgical hub 5104 could then adjust the RF power level or the ultrasonic amplitude of the generator (e.g., “energy level”) to compensate for the fluid filled environment. Relatedly, the type of tissue being operated on can affect the optimal energy level for an ultrasonic surgical instrument or RF electrosurgical instrument to operate at. A situationally aware surgical hub 5104 could determine what type of surgical procedure is being performed and then customize the energy level for the ultrasonic surgical instrument or RF electrosurgical instrument, respectively, according to the expected tissue profile for the surgical procedure. Furthermore, a situationally aware surgical hub 5104 can be configured to adjust the energy level for the ultrasonic surgical instrument or RF electrosurgical instrument throughout the course of a surgical procedure, rather than just on a procedure-by-procedure basis. A situationally aware surgical hub 5104 could determine what step of the surgical procedure is being performed or will subsequently be performed and then update the control algorithms for the generator and/or ultrasonic surgical instrument or RF electrosurgical instrument to set the energy level at a value appropriate for the expected tissue type according to the surgical procedure step.

In examples, data can be drawn from additional data sources 5126 to improve the conclusions that the surgical hub 5104 draws from one data source 5126. A situationally aware surgical hub 5104 could augment data that it receives from the modular devices 5102 with contextual information that it has built up regarding the surgical procedure from other data sources 5126. For example, a situationally aware surgical hub 5104 can be configured to determine whether hemostasis has occurred (e.g., whether bleeding at a surgical site has stopped) according to video or image data received from a medical imaging device. The surgical hub 5104 can be further configured to compare a physiologic measurement (e.g., blood pressure sensed by a BP monitor communicably connected to the surgical hub 5104) with the visual or image data of hemostasis (e.g., from a medical imaging device communicably coupled to the surgical hub 5104) to make a determination on the integrity of the staple line or tissue weld. The situational awareness system of the surgical hub 5104 can consider the physiological measurement data to provide additional context in analyzing the visualization data. The additional context can be useful when the visualization data may be inconclusive or incomplete on its own.

For example, a situationally aware surgical hub 5104 could proactively activate the generator to which an RF electrosurgical instrument is connected if it determines that a subsequent step of the procedure requires the use of the instrument. Proactively activating the energy source can allow the instrument to be ready for use as soon as the preceding step of the procedure is completed.

The situationally aware surgical hub 5104 could determine whether the current or subsequent step of the surgical procedure requires a different view or degree of magnification on the display according to the feature(s) at the surgical site that the surgeon is expected to need to view. The surgical hub 5104 could proactively change the displayed view (supplied by, e.g., a medical imaging device for the visualization system) accordingly so that the display automatically adjusts throughout the surgical procedure.

The situationally aware surgical hub 5104 could determine which step of the surgical procedure is being performed or will subsequently be performed and whether particular data or comparisons between data will be required for that step of the surgical procedure. The surgical hub 5104 can be configured to automatically call up data screens based upon the step of the surgical procedure being performed, without waiting for the surgeon to ask for the particular information.

Errors may be checked during the setup of the surgical procedure or during the course of the surgical procedure. For example, the situationally aware surgical hub 5104 could determine whether the operating theater is setup properly or optimally for the surgical procedure to be performed. The surgical hub 5104 can be configured to determine the type of surgical procedure being performed, retrieve the corresponding checklists, product location, or setup needs (e.g., from a memory), and then compare the current operating theater layout to the standard layout for the type of surgical procedure that the surgical hub 5104 determines is being performed. In some exemplifications, the surgical hub 5104 can compare the list of items for the procedure and/or a list of devices paired with the surgical hub 5104 to a recommended or anticipated manifest of items and/or devices for the given surgical procedure. If there are any discontinuities between the lists, the surgical hub 5104 can provide an alert indicating that a particular modular device 5102, patient monitoring device 5124, HCP monitoring devices 35510, environment monitoring devices 35512, and/or other surgical item is missing. In some examples, the surgical hub 5104 can determine the relative distance or position of the modular devices 5102 and patient monitoring devices 5124 via proximity sensors, for example. The surgical hub 5104 can compare the relative positions of the devices to a recommended or anticipated layout for the particular surgical procedure. If there are any discontinuities between the layouts, the surgical hub 5104 can be configured to provide an alert indicating that the current layout for the surgical procedure deviates from the recommended layout.

The situationally aware surgical hub 5104 could determine whether the surgeon (or other HCP(s)) was making an error or otherwise deviating from the expected course of action during the course of a surgical procedure. For example, the surgical hub 5104 can be configured to determine the type of surgical procedure being performed, retrieve the corresponding list of steps or order of equipment usage (e.g., from a memory), and then compare the steps being performed or the equipment being used during the course of the surgical procedure to the expected steps or equipment for the type of surgical procedure that the surgical hub 5104 determined is being performed. The surgical hub 5104 can provide an alert indicating that an unexpected action is being performed or an unexpected device is being utilized at the particular step in the surgical procedure.

The surgical instruments (and other modular devices 5102) may be adjusted for the particular context of each surgical procedure (such as adjusting to different tissue types) and validating actions during a surgical procedure. Next steps, data, and display adjustments may be provided to surgical instruments (and other modular devices 5102) in the surgical theater according to the specific context of the procedure.

Systems, methods, and instrumentalities are disclosed for surgical procedure data processing and creating a record of the processing for archival in metadata associated with the results of the processing. The processing may include transforming the data. For example, processing surgical procedure data may include using a transformation or algorithm. The transformation or algorithm may combine or compile multiple data elements together. Transforming the surgical procedure data may generate transformed surgical procedure data. Information associated with the transforms used for processing the surgical procedure data may be archived, for example, in metadata associated with the transformed surgical procedure data. The metadata may be annotated with information associated with transforms performed on the transformed surgical procedure data. The metadata may be stored with the transformed surgical data.

For example, a surgical hub may obtain surgical procedure data associated with a patient. The surgical hub and/or hub may be the surgical hub 20002 as described herein with respect to FIG. 2 . The surgical hub may obtain the surgical procedure data from one or more of a module associated with the surgical hub, a surgical system located in the OR, and/or the like. The surgical hub may process the obtained surgical procedure data. For example, the surgical hub processing the surgical procedure data may include transforming the surgical procedure data. The surgical hub may generate transformed surgical procedure data using a transform. The surgical procedure may generate metadata associated with the transformed surgical procedure data. The metadata may include information associated with the processing (e.g., transform) performed on the surgical procedure data that was used in generating the transformed surgical procedure data. The metadata may include information such as a time associated with the processing of the surgical procedure data, a location associated with the processing of the surgical procedure data, information indicating a portion of the surgical procedure data that was processed, a revision of the transform used to perform the transformation, and/or the like. The surgical hub may process the surgical procedure data and/or generate metadata associated with the transformed surgical procedure data, for example, using blockchain recording. The surgical hub may store the transformed surgical procedure data and the metadata comprising the processing information.

The surgical hub may annotate metadata, for example, for transforms of surgical procedure data tied to transformed surgical procedure data. The annotated metadata may be used for tracking and interpreting the transformed data. For example, metadata associated with transformed surgical procedure data may allow for interpretation of the transformed surgical procedure data. HCPs may use the metadata to interpret the result of a transformation, for example. The surgeon may use the metadata to determine the raw surgical procedure data before processing.

FIG. 9 illustrates an example processing of surgical procedure data and annotation of metadata associated with the processed surgical procedure data. A surgical hub may obtain surgical procedure data. A surgical hub may process obtained surgical procedure data. The surgical procedure data may be associated with respective metadata. The respective metadata may include information associated with transforms performed on the surgical procedure data set(s). The metadata may comprise metadata blocks. The metadata blocks may be subsets of the metadata. For example, a metadata block may be associated with a first transformation and a second metadata block may be associated with a second transformation. The surgical hub may process the surgical procedure data set(s). Using the transformation, the surgical hub may generate a result. The surgical hub may annotate metadata associated with the generated result, for example, based on the performed processing on the surgical procedure data set(s).

For example, as shown in FIG. 9 , surgical procedure data sets, such as data set #1 43050, data set #2 43052, and data set #3 43054, may be processed. Each surgical procedure data set may be associated with respective metadata. The metadata may comprise metadata block(s). The metadata block(s) may include information associated with transforms used on the surgical procedure data set(s) For example, data set #1 43050 may be associated with a first metadata block 43056, data set #2 43052 may be associated with a second metadata block 43058, and data set #3 may be associated with a third metadata block 43060. For example, the first metadata block 43056 associated with data set #1 43050 may include information associated with the previous transforms performed on data set #1 43050, such as transform #1. For example, the second metadata block 43058 associated with data set #2 43052 may include information associated with the previous transforms performed on data set #2 43052, such as transform #2. For example, the third metadata block 43060 associated with data set #3 43054 may include information associated with the previous transforms performed on data set #3 43054, such as transform #3.

Surgical procedure data sets may be processed, for example, by a surgical hub. The processing may include combining the surgical procedure data sets, for example. The processing may include compiling data elements together. The processing may include using a transform and/or algorithm on the surgical procedure data set(s). The transformation may include synchronizing the surgical procedure data sets. For example, as shown at 43062 in FIG. 9 , the surgical procedure data sets may be transformed using a Σ transformation, which may include combining the surgical procedure data sets. A fourth metadata block 43064 may be associated with the raw surgical procedure data used for the Σ transformation (e.g., the surgical procedure data sets before undergoing the Σ transformation). The fourth metadata block 43064 may include the information associated with the processing and/or transformations performed on the raw surgical procedure data used for the Σ transformation, such as any transformations that were performed on the surgical procedure data sets. For example, the fourth metadata block 43064 may include information associated with transform #1, transform #2, and transform #3, which may have been performed on the surgical procedure data sets.

The Σ transformation may generate transformed surgical procedure data, for example, using the Σ transformation. The transformed surgical procedure data may be the combination of the surgical procedure data sets and/or the compiled data elements of the surgical procedure data sets. For example, the transformed surgical procedure data from the Σ transformation may be the summation of the surgical procedure data sets. Metadata associated with the transformed surgical procedure data, may be generated, for example, by a surgical hub. The metadata may include information associated with the performed Σ transformation. The metadata associated with the performed Σ transformation may be included in a metadata block. The metadata block associated with the performed Σ transformation may be a different metadata block than the fourth metadata block 43064 associated with the transforms performed on the raw surgical procedure data. The information associated with the performed Σ transformation may be added to the metadata associated with the raw surgical procedure data (e.g., the fourth metadata block 43064). For example, the raw surgical procedure data for the Σ transformation was associated with metadata that included information about the transforms performed on the raw surgical procedure data (e.g., transform #1, transform #2, and transform #3). The metadata may be modified and/or annotated to include the Σ transformation. For example, as shown at 43068, the metadata associated with the transformed surgical procedure data from the Σ transformation may include information associated with transform #1, transform #2, transform #3, and the Σ transformation. The metadata may include separate metadata blocks associated with the individual transforms used. For example, as shown at 43068, the metadata may include two separate metadata blocks. The two separate metadata blocks in combination may enable interpretation of the history of transforms used on the data sets. The transformed surgical procedure data from the Σ transformation and the associated metadata may be stored, for example. The transformed surgical procedure data from the Σ transformation may undergo further processing, for example.

As shown at 43066 in FIG. 9 , the transformed surgical procedure data from the Σ transformation may be transformed further, for example, using a second transform, such as an inverse transform (e.g., 1/X transform). The transformed surgical procedure data from the Σ transformation used for the inverse transform (e.g., the input to the inverse transform) may be associated with metadata, which may include information associated with the transforms performed on the transformed surgical procedure data from the Σ transformation, such as shown at 43068. The inverse transform process may generate a result 43070. The inverse transform process may generate metadata associated with the result 43070, for example, as shown at 43072. The metadata may include information about the performed process, for example, such as the inverse transform. The metadata may comprise separate metadata blocks associated with the individual transforms performed. The metadata may include information associated with the transforms performed on the result 43070. For example, as shown in FIG. 9 at 43072, the metadata may include information associated with transform #1, transform #2, transform #3, the Σ transform, and the inverse transform. The metadata may indicate the processing history of the result.

For example, the surgical hub may obtain previously stored transformed surgical procedure data. The surgical hub may obtain previously stored transformed surgical procedure data and metadata associated with the previously stored transformed surgical procedure data. The surgical hub may transform the previously stored transformed surgical procedure data. The surgical hub may generate updated metadata associated with the transformation of the previously stored transformed surgical procedure data. The surgical hub may generate updated metadata based on the transformed used on the previously stored transformed surgical procedure data and/or metadata associated with the previously stored transformed surgical procedure data. For example, the updated metadata may include the transform(s) used on the previously stored transformed surgical procedure data prior to storage and the updated metadata may include the transform(s) used on the previously stored transformed surgical procedure data.

The metadata associated with transformed surgical procedure data may be editable. For example, the metadata may be updated based on subsequent transforms performed on a surgical procedure data set. The surgical hub may process surgical procedure data multiple times. The surgical hub may update the metadata associated with the surgical procedure data based on each process performed. For example, the surgical hub may update the metadata to include information associated with each transform used on the surgical procedure data.

Metadata may include information associated with a revision associated with the transform performed on surgical procedure data. For example, a transform may be associated with a revision. The revision may be a revision number. The revision may indicate the version of the transform used on the surgical procedure data. A transform that has been updated may be associated with a different revision and/or revision number. For example, a transform may be updated from a first version to a second version. The first version may be associated with a first revision number and the second version may be associated with a second revision number. The revision number may be used to determine the version of the transform that was used. The metadata associated with transformed surgical procedure data may include information associated with the revision and/or revision number of the transform. For example, the metadata may be used to determine the version of the transform based on the revision information. The revision may be used to interpret the transformed data, for example, because the revision number may indicate whether the transform used for the processing was an older version or an updated version.

The surgical hub may transform the surgical procedure data associated with a revision number. The metadata may include information associated with the transform performed on the surgical procedure data. The information associated with the transform may include the revision number associated with the transform. The metadata may be used to determine the transform performed on the surgical procedure data and/or the revision number of the transform performed on the surgical procedure data.

Metadata may include information associated with where the surgical procedure data was processed and/or transformed. For example, the metadata may include information associated with a location where the processing and/or transformation of the surgical procedure data occurred. The metadata may include information associated with a processing tier that transformed the surgical procedure data. For example, the metadata may include information indicating that the transformation was performed at the surgical hub, the edge tier, the cloud tier, and/or the like. The metadata may include information associated with a module and/or surgical system that processed the surgical procedure data.

For example, a surgical hub may perform a first transform on surgical procedure data and generate metadata associated with the first transform on the surgical procedure data. The metadata may include information indicating that the first transform was performed in the surgical hub. The transformed surgical procedure data and associated metadata may be sent to the edge tier for further processing. The previously transformed surgical procedure data may undergo a second transform in the edge tier and generate twice-transformed surgical procedure data. Updated metadata associated with the twice-transformed surgical procedure data may be generated based on the second transform and the existing metadata. The updated metadata may include information indicating that the second transform was performed at the edge tier. The updated metadata may include information associated with both the first and second transform, such as, for example, that the first transform was performed at the surgical hub and the second transform was performed at the edge tier. The metadata may be used to determine in which tier each transformation occurred.

Metadata may include information associated with a time when the surgical procedure data was processed and/or transformed. Metadata may include information associated with data used to transform the surgical procedure data. For example, a process and/or transform may use data to process and/or transform surgical procedure data.

For example, the surgical hub may transform the surgical procedure data partially. For example, the transform may be performed on a portion of the surgical procedure data such that a subset of the surgical procedure data is transformed. Metadata may be generated based on the partial transformation. The metadata may include information associated with the partial transformation. For example, the metadata may include information indicating the portion (e.g., subset) of the surgical procedure data that was transformed. The metadata may be used to interpret which portion of the surgical procedure data was transformed.

Blockchain recording may be used. Blockchain recording may use a distributed database. For example, blockchain recording may be used for record keeping. Blockchain may refer to a chain of blocks that contain information. Each block in the chain of blocks may contain information about digital information. The blocks in the chain may include previous information about the digital information. A block may be attached to the blockchain to add information to the digital information. Blockchain may be used for the secure transfer of digital information, such as medical data, for example.

For example, a surgical hub may transform surgical procedure data, for example, using blockchain recording. The surgical hub may generate, annotate, and/or modify metadata associated with the transformed surgical procedure data using blockchain recording. The metadata associated with the transformed surgical procedure data may include blockchain, for example, blocks of information associated with the transformations performed on the surgical procedure data. Information associated with the transform used to process the surgical procedure data may be added to the blockchain, in a block, for example.

Surgical procedure data associated with a surgical system may be processed and/or transformed, for example, in preparation to be sent to a different surgical system and/or data tier. For example, the surgical system and/or data tier may be included in the surgical specific sub-network tier system 40052, as described herein with respect to FIG. 1B. For example, the surgical sub-systems may be grouped by the type of surgical procedures and/or other departments in a medical facility or hospital (e.g., surgical procedure specific departments, ER departments, colorectal departments, bariatric departments, thoracic departments, and/or billing departments). Metadata associated with the transformed surgical procedure data may be sent with the transformed surgical procedure data. Transformed surgical procedure data may be sent to a different data tier, for example, to be further processed and/or stored. The data tier may be the edge tier, a manufacturer cloud tier, a surgical hub tier, an HCP tier, and/or the like. Transformed surgical procedure data may be sent to HCPs (e.g., surgeons) for interpretation and/or analysis. The surgical hub may determine a data tier to be used for storing and/or further processing the transformed surgical procedure data and the metadata associated with the transforms used on the surgical procedure data. The surgical hub may select a data storage, for example, based on the data tier. The surgical hub may select multiple data storages, for example. The surgical hub may store the transformed surgical procedure data and the metadata associated with the transformation (e.g., including information associated with the transform used on the surgical procedure data), using the selected data storage.

For example, the surgical hub may determine the data tier to be used to store and/or process the transformed surgical procedure data and the metadata associated with the transformed surgical procedure data. The data tier to be used may be based on the type of data, how the data will be used, security classification of the surgical procedure data, and/or the like. For example, if the surgical procedure data requires additional processing, the surgical hub may determine to send the surgical procedure data and metadata to the edge tier. The edge tier may provide more efficient processing. The surgical hub may determine to use the edge tier, for example, based on the HIPAA boundary. For example, the edge tier may be determined to be used for private health information. The surgical hub may determine to use the surgical hub tier, for example, for surgical procedure data relating to procedure simulations and/or user settings for surgical procedures. Surgical instrument settings and OR layout information may be stored in the surgical hub tier, for example, such that future surgical procedures may easily access the information. The surgical hub may determine to use the HCP tier, for example, to enable HCPs to interpret and/or analyze the transformed surgical procedure data. The surgical hub may determine to use the manufacturer's cloud tier, for example, for long-term data storage. The surgical hub may determine to use the manufacturer's cloud tier, for example, for non-HIPAA data.

The surgical hub may encrypt the transformed surgical procedure data, for example, based on the determined data tier. For example, surgical procedure data may be encrypted before transferring to a different data tier. Data tiers, such as the cloud tier, may be outside the HIPAA boundary. Surgical procedure data sent to a device outside the HIPPA boundary may be encrypted to provided extra security precautions, for example.

For example, the surgical hub may determine to use the manufacturer's cloud tier data tier for the transformed surgical procedure data and the metadata. Based on the determination, the surgical hub may encrypt the transformed surgical procedure data and the metadata, for example, because the manufacturer cloud tier is outside the HIPAA boundary. For example, the surgical hub may determine to use the surgical hub storage for the transformed surgical procedure data and the metadata. Based on the determination, the surgical hub may send the transformed surgical procedure data and the metadata without encryption, for example, because the surgical hub storage is within the HIPAA boundary.

FIG. 10 illustrates an example data tier determination for transformed surgical procedure data and the metadata associated with the transformed surgical procedure data. For example, as shown in FIG. 10 , surgical procedure data may include a first audio file 43100, second audio file 43102, third audio file 43104, first video file 43106, second video file 43108, and HCP data 43110. The surgical procedure data may be transformed, for example, by a surgical hub. A data tier may be determined for the transformed surgical procedure data. The transformed surgical procedure data may be sent to the determined data tier.

As shown at 43112, the surgical procedure data may be processed and/or transformed. The processing and/or transformation may include storing a copy of the raw surgical procedure data. The processing and/or transformation may include synchronizing the surgical procedure data sets. Synchronizing the surgical procedure data sets may enable interpretation of the surgical procedure data sets. The processing and/or transformations may include compiling data elements, combining the surgical procedure data sets, and/or similar processing and transforms, for example, as described herein. Metadata may be generated based of the processing and/or transformations performed on the surgical procedure data. As shown at 43114, the metadata may include the processes and/or transformations performed on the transformed surgical procedure data.

As shown at 43116, a data tier may be determined, for example, to send the transformed surgical procedure data. Multiple data tiers may be determined. The data tiers may include, for example, the manufacturer's cloud tier 43118, the edge tier 43122, the surgical hub storage tier 43126, the surgeon tier 43130, and/or the like. The data tier may be determined, for example, based on the surgical procedure data and the metadata associated with the surgical procedure data (e.g., as shown at 43114). The edge tier may be determined, for example, to enable additional processing on the surgical procedure data. The surgical hub storage tier may be determined for example, if the surgical procedure data includes user preferences for surgical procedures, OR setup layout and/or plans, surgical instrument instructions and/or settings, and/or the like.

Based on the determined data tier, encryption for the surgical procedure data sets may performed. For example, encryption may be performed on surgical procedure data sets that may be sent to data tiers outside the HIPAA boundary, such as the cloud tier (e.g., manufacturer's cloud tier). If the surgical procedure data is sent within the HIPAA boundary, encryption may be skipped.

If encryption is performed, the metadata associated with the transformed surgical procedure data may be updated, for example, to include information about the performed encryption. For example, the surgical hub may determine to send the transformed surgical procedure data and metadata associated with the transformed surgical procedure data to the manufacturer's cloud tier. Based on the manufacturer's cloud tier determination, the transformed surgical procedure data and the metadata associated with the transformed surgical procedure data may be encrypted. The metadata associated with the transformed surgical procedure data may be updated to include the encryption. The encrypted transformed surgical procedure data and the updated metadata may be stored in the manufacturer cloud tier. As shown at 43120, the updated metadata may include the previous transformations associated with the stored surgical procedure data, including the encryption.

For example, the edge tier and/or surgical hub storage tier may be determined as the data tier to store the surgical procedure data. The surgical hub may skip encryption, for example, because the edge tier and the surgical hub storage are within the HIPAA boundary. The surgical hub may store the transformed surgical procedure data in the edge tier and/or the hub storage. The metadata (e.g., as shown in 43124 and 43128) associated with the transformed surgical procedure data may be stored with the transformed surgical procedure data. The metadata may not include information indicating encryption, for example, because encryption was not performed on the transformed surgical procedure data.

In an example, the surgical hub may obtain a procedure plan. The procedure plan may have been created in the edge processing network. The procedure plan may be created in the edge processing network based on collected surgical procedure data from previous surgical procedures. For example, the edge processing network may collect surgical procedure data from previous surgical procedures and develop a simulation to emulate a predicted surgical procedure. The model surgical procedure may be used to compare to surgical procedures performed in the future. The model surgical procedure may be used as guidance for future surgical procedures.

The surgical hub may send surgical procedure data to the edge processing network, for example, for the edge processing network to create procedure plans. The surgical hub may organize the surgical procedure data for the edge processing network's use, for example, in creating the procedure plans. The surgical procedure data sent to the edge processing network may expand the edge processing network's data set and accessible information. Expanded data sets and accessible information may allow the edge processing network to create a more accurate and/or better procedure plan for the surgical procedure.

The surgical hub may simulate the procedure plan, for example, during a surgical procedure. The simulated procedure plan may allow the surgical hub to follow patterns in the procedure plans. The simulated procedure plan may allow the surgical hub to look for deviations within the performed surgical procedure. For example, the surgical procedure may encounter an event that deviates from the procedure plan. The procedure plan may provide added information for the surgical procedure to the surgical hub.

FIG. 11 illustrates an example process for transforming surgical procedure data and generating metadata associated with the transformed surgical procedure data for storage. As shown at 43200, surgical procedure data may be obtained. The surgical procedure data be associated with a patient. The surgical procedure data may be obtained from a module associated with the surgical hub and/or a surgical system within the OR. The surgical procedure data may be obtained from a data storage.

As shown at 43210, the surgical procedure data may be processed, for example, using transformations and/or algorithms. The transformations and/or algorithms may combine and/or compile multiple data elements together. The surgical procedure data may be processed, for example, to generate transformed surgical procedure data.

As shown at 43220, metadata may be generated, for example, based on the transform used on the surgical procedure data. The metadata may include information associated with the transformation that was performed on the surgical procedure data. The metadata may include information associated with previous transformations.

As shown at 43230, the transformed surgical procedure data and metadata may be stored, for example, in a data storage and/or data tier. The data storage may be a local OR data storage, the surgical data storage, an edge tier data storage, a cloud tier data storage, a department specific data storage, a facility specific data storage, and/or the like. The transformed surgical procedure data and metadata may be stored for future use. For example, the surgical procedure data may be further processed, and the metadata may be updated based on the further processing.

Tasks performed during a surgical procedure may be prioritized. Tasks performed during the surgical procedure may include data processing, communication, a surgical hub response, surgical procedure tasks, and/or the like. For example, the surgical hub may perform data processing, data communication, and controlling surgical instruments (e.g., simultaneously) during a surgical procedure. The surgical hub may prioritize the controlling of the surgical instruments over the data processing and data communication. For example, the surgical hub may determine to pause data processing and/or data communication based on the surgical procedure reaching a critical procedure step.

Tasks performed during a surgical procedure may be prioritized, for example, based on the classification of the surgical procedure task. For example, the classification of surgical procedure task(s) may be associated with the risk and/or harm level of the surgical procedure task performed. The priority of the surgical hub response and interaction with surgical equipment and/or surgical devices attached to the surgical hub may be determined based on the risk and/or harm level that is imparted on the patient or user. The classifications of the surgical procedure tasks may be cosmetic, moderate, serious, or critical (e.g., life threatening). The surgical hub may prioritize interactions with surgical devices and/or equipment that involve critical surgical procedure tasks.

The surgical hub may use situational awareness, for example, based on obtained surgical procedure data, to determine classification types for surgical procedure tasks. The surgical hub may be included in the situationally aware surgical system 5100 as described herein with respect to FIG. 8 . Situational awareness may enable the surgical hub to derive and/or infer information related to the surgical procedure, for example, based on received data. The surgical hub may determine the current surgical procedure step and/or current risk level of the surgical procedure. Based on the determined classification types, the surgical hub may determine priorities associated with the surgical procedure tasks. The surgical hub may modify its interactions with coupled modules, surgical equipment, and/or surgical devices, based on the priorities associated with the surgical procedure tasks.

For example, the surgical hub may be performing a first task and a second task. The surgical hub may use situational awareness to determine a first classification type associated with the first task and a second classification type associated with the second task. The surgical hub may determine a first priority based on the first classification type and a second priority based on the second classification type. The surgical hub may determine that the first priority is higher than the second priority. The surgical hub may pause the second task based on the determination that the first priority is higher than the second priority.

For example, a surgical hub may pause data processing and/or data communication to perform a different surgical procedure task. An energy device may be used for manipulation of tissue and to apply therapeutic treatment. If the energy device is used for grasping and manipulating tissue that may be classified as cosmetic or moderate harm, the hub may perform other tasks, such as data processing and/or data communication, simultaneously. The surgical hub may complete the data processing and/or data communication in real time (e.g., at the time surgical procedure data is generated) and/or place the data processing and/or data communication in a holding spot until the other surgical procedure task was completed. If the energy device and/or other interfacing device is applying therapeutic treatment, which may be classified as critical or serious harm, the hub may pause data processing or communication, for example, until the critical and/or serious task was completed. The pausing may ensure no interruptions and/or delays with power and/or communication would disrupt the critical and/or serious task.

For example, situational awareness may affect prioritization of tasks performed during surgical procedures. The surgical procedure data monitored from a module and/or system (e.g., or data obtained from the data sources 5126 as described herein with respect to FIG. 8 ) may change the prioritization to be higher, for example based on the utilization of that surgical procedure data by another high priority system. The surgical procedure data monitored from a module and/or system may change the prioritization of a task, for example, if the surgical procedure data is used in combination with another device and/or system to complete a task. The surgical hub may identify surgical equipment and/or devices attached to the system that may work in combination. The surgical hub may reassign priority of a system, for example, based on the risk and/or impact the system may have on the next procedural steps in the surgical procedure. For example, the surgical hub may obtain smoke evacuation control data. The smoke evacuation control data may affect the prioritization of the advanced visualization system, for example, to project surgeon critical structure data adjacent to and/or onto an occluded instrument shaft.

For example, the surgical hub may identify that the surgeon's visualization display, energy device, and smoke evacuation system is paired. Prioritization of the smoke evacuation system may normally be lower than the priority of the surgeon's visualization display and the priority of the energy device. The surgical hub may reassign the prioritization to alter the priority status based on a system risk and/or harm, which may improve the outcome of the next surgical procedure step.

In an example, the surgical hub may reassign priority between the visualization display, energy device, and smoke evacuation system. The surgical hub may identify the next user step (e.g., procedure step) to include applying energy to seal a vessel. The smoke evacuation control data stream may be used for the advanced visualization system, for example, to project surgeon critical structure data adjacent and/or onto an occluded instrument shaft. The surgical hub may identify, based on the smoke evacuation system working in conjunction with the visualization system and the energy device activation, that the user's field of view is obstructed with smoke plumb. Based on the obstruction, the surgical hub may reassign priority such that the smoke evacuation may take priority over the energy activation (e.g., where normally the energy activation is a higher priority than the smoke evacuation), for example, to clear the view of the user prior to activating energy on the device. Reprioritizing the smoke evacuation may minimize the risk and/or harm of the user applying energy to unintended areas, such as vessels or critical structures.

In an example, the surgical hub may reassign priority between the visualization system, energy device, and smoke evacuation system. The surgical hub may identify that the next procedure step is to apply energy to dissect. The surgical hub may determine that no vessels and/or critical structures are within the surrounding area (e.g., surgical site). For example, the surgical hub may determine the surrounding area includes tissue or fat. The surgical hub may allow the energy to be applied and refrain from changing the smoke evacuation to a higher priority.

Automated transcriptions may be provided for recorded audio. The surgical hub may transcribe verbal information created by the surgeon and/or HCPs in the operating room. The transcription may be linked to stored video of the surgical procedure. The automated transcription may be used to document issues or document key data points, for example, in the surgical procedure.

The surgical hub may receive surgical procedure data, such as audio files and/or video files. The audio files may be obtained from audio recorders and/or microphones, which may be placed in the OR and/or worn by the surgeons and/or HCPs. Smart wearable devices may be work by surgeons and/or HCPS to record OR conversations. The video files may be obtained from cameras in the OR.

The surgical hub may perform processes on the surgical procedure data to generate transcriptions. For example, the surgical hub may synchronize the surgical procedure data sets, such as the audio data and the video data. The audio may be synchronized with modules, surgical systems, surgical devices, and/or other OR systems. For example, the audio may be synchronized with generator data. For example, the audio may be synchronized with a surgical data recording, management, and learning system, such as the C-SATS system.

Automated transcriptions may be created, for example, off the video in real time. Automated transcriptions off the video in real time may be transcribed, for example, into a different language. The automated transcriptions may allow a user watching the video to both view the surgical procedure and view what is being said in the OR. The transcriptions may allow better interpretation of the surgical procedure. For example, an observer may speak a different language than is being spoken in the OR during the surgical procedure. The automated transcriptions may translate the audio to the observer's native language to allow better understanding of occurrences in the OR.

Automated transcriptions may be created, for example, and transposed and stored for access in the future. The transcriptions may be translated. The translation may be transposed over the associated video file, for example, similar to closed caption. The transposed translation may allow users to watch and understand the recorded surgical procedure.

The automated transcriptions may be edited. The surgery environment is unrehearsed, which may lead to incorrect statements being spoken, for example. Many things may be spoken incorrectly or not said at all due to focus on the event or action. An automated transcription may enable users to review the audio and video. Based on the reviewed audio and video, the transcription may be edited, corrected, and/or added to, before storing the files. For example, the files may be used for training and/or instructional purposes. Correcting the audio files used for training before storing the files would prevent incorrect audio files being used.

FIG. 12 illustrates an example transcription of audio from an OR during a surgical procedure. Original audio 43300 may be generated during the surgical procedure. The original audio 43300 may be transcribed at 43302. The transcription may include training the audio data. The transcribed audio may be sent to a data storage 43304. The audio transcription may be enriched, for example, as shown at 43306. The audio transcription may sent to a checking and correction user interface 43308, for example, to be checked for errors and corrected. Static output generation may be performed at 43310, for example, based on the transcribed audio. The static output generation may create subtitles 43312 and/or a static webpage 43314. As shown at 43316, a full text search may be performed on the transcribed audio. The full text search information may be sent to a dynamic webpage 43318.

For example, the enrichment of the transcribed audio may include natural language processing. Natural language processing may include using artificial intelligence to understand the text and spoken words in the transcribed audio. Natural language processing may use computational linguistics with statistical, machine learning, and/or deep learning models. The transcribed audio may be processed to determine the meaning and/or intent of the speaker(s) in the transcribed audio. Natural language processing may include speech recognition, speech/grammar tagging, word sense disambiguation, named entity recognition, co-reference resolution, sentiment analysis, natural language generation, and/or the like. For example, the enrichment may be performed to determine summaries of the transcribed audio.

For example, the checking and correction user interface 43308 may process the transcribed audio. The user interface may check for errors within the transcribed audio. If the user interface detects error(s), the user interface may correct the transcribed audio and store the corrected transcription in the data storage.

Scalable processing may be performed. For example, scalable processing may be performed using scalable processing modules. Scalable processing modules may be used for individual and/or cooperative use within a surgical hub. Cooperative couple of scalable processing modules may enable the modules to share processing needs. For example, if multiple modules are connected within the same surgical hub, the modules may be capable of pairing together to cooperatively operate. The modules may share their combined processing capacity to augment the surgical hub modules. The modules may share their combined processing capacity to augment the surgical hub modules, for example, in a prioritized fashion.

Scalable processing may be performed, for example, using a processor module. The processor module may supplement other surgical hub modules, for example, by providing surge processing. Scalable distributed processing may be provided, for example, for processing tasks by other surgical hub attached modules and/or systems. Scalable distributed supplemental processing modules may distribute processing needs of a surgical hub system and/or attached surgical hub module. Scalable distributed supplemental processing modules may share processing capabilities of the surgical hub, for example, to increase or supplement processing capabilities within the module or surgical hub. Scalable distributed processing may be used, for example, to signal process data from biometric sensors, which may not have intelligence, processing capabilities, and/or storage capabilities.
